Re: Firefox Developer Edition
Ingelore Clason
One of the biggest pain points for developers is having to use numerous siloed development environments in order to create engaging content or for targeting different app stores. For these reasons, developers often end up having to bounce between different platforms and browsers, which decreases productivity and causes frustration.
I guess Mozilla feels the dev tools are mature enough in, what was, Aurora; and they want to get developers using the new tools sooner. Which, really, will lead to more tool feedback, which will lead to better tools.
Why in the world I use browser created by people who are so [REDACTED] that they cannot develop video presentation in format which they would actually support (yes, I am on 31ESR)? Do I have to download Chrome just to see videos by Mozilla? Guys!
With this update, I lost everything. All my cookies, all by bookmarks, all saved data.
Forefox now acts likle a completely fresh install.
Is there anything I can do to get my data back?
It would have been nice to opt out of this to save my data before the update.
Firefox Developers addition just installed from Aurora and it changed my layout and got rid of every bookmark and plugin wtf some one tell me how to make it like it was I like the black but could have at least left the layout i had.
I want to develop a specific feature for the web browsers including chrome and firefox. I am new to this area, but have some good ideas as to what features should be available on a standard browser,
Could you please suggest me how to achieve it, I dont know web programmaing, Would really appreciate your help.
Thanks
1) It cannot have tabs for the files you are working with in a debug session. When you have dozens or hundreds of JS files in your project, this makes it very difficult to work with just 2, 3, or 4 of those files in a debug session.
2) The same kind of thing applies to the breakpoints being listed under the files in the side list. When you have breakpoints set in a large list of files, it would be really annoying to use that debugger for toggling those breakpoints on and off. Chrome puts the breakpoints in its own section so they are all together and easy to switch to when debugging.
3) The visual stack path at the top is pretty much a waste since you have the call stack tab that shows the same type of information. Using that space to have the files on tabs that you are working with would be a far more useful feature.
Great work. I have been using developer version since it came out. I like the new flat theme and that you gave users a choice of light or dark theme. quite spiffy. I find the network tab very helpful.
The main issue for me (that is ultimately making the decision to consider actively using it very hard) is performance. Getting a lot of cpu spikes pushing over 100%. Mostly when using the developer tools, or viewing a website using any kind of CSS animation.
I would like to know how to keep Firefox for my opening page were his tail swirls around the world and his body.When I connect to Firefox and the internet the Firefox comes on with a swirl. I think that is cute and exciting. How do I keep that? Please let me know. Sincerely, Caryn Merritt email: cemer...@yahoo.com
I have been using the program for a couple of days and so far it sounds great.
The dark theme is fantastic, and you have a lot of information and tools for any task at hand!
Just a single suggestion at a glance: using the element picker tool, it would be nice if the Web developer tools window came back on top after clicking with the mouse on the object to be examined.
Anyway, a great job. Thank you!
My name is Juan Sebastian Ruiz Casas. Im studing desing web with CSS and Javascript de WebApps, incl. mviles FirefoxOS, but dont understand totally.
I do want understand the desing. Can you help me?
My main problem with it is an aesthetic one. The Inspector stacks the HTML and CSS windows horizontally when under 700px wide, but automatically jumps them to a side-by-side view once the inspector gets to over 700px wide.
I've been at this for hours now. Nothing works, .desktop file below. I don't know why, but I can't drag&drop the open firefox-dev icon to my favorites, only when I look for it in Applications windows and drag it from there. But that way it just opens a new icon instead. Before this issue gets closed for a mildly similar question, below are all of the solutions I've tried.
This answer you linked to, Firefox developer edition icon duplication in Gnome shell, helped me solve this issue, here's my /usr/share/applications/firefox-developer-edition.desktop (the naming could be relevant, not sure):
I've downloaded the regular firefox, and see no difference. All of these tools are in it, so it seems to me that with aurora channel I get an unstable something what is just impede in my work instead it helps me.
Naturally, the beta or alpha versions may be less stable than the general production release, so you can make your decision on which version to use based on how beneficial it is to get new features and developer tools a bit earlier than they'd otherwise be available.
One major difference is that when you install Firefox Developer Edition it doesn't take precedence over any existing version of Firefox installed on your machine. With Nightly and Beta, they become the default version of FF. This means you can run Firefox Developer and standard/nightly/beta Firefox concurrently.
I get a "Software is Preventing Firefox Developer Edition From Safely Connecting to This Site" (DigiCert Global Root CA) (MOZILLA_PKIX_ERROR_MITM_DETECTED) error and there is no way to add an exception.
It works again when I downgrade firefox but doing that I cannot use my normal firefox profile anymore, cause the "firefox version I am trying to use is too old, please create a new profile" which I don't want to do.
ecurity.enterprise_roots.enabled is not set to true. Did mozilla change anything with firefox with the last update so that would be necessary? As I said, the downgraded firefox version works as usual. I would try it but I am not exactly sure what the implications are exactly.
I get this error from time to time. Not sure what makes them appear. Fastmail.com and :AddRootToFirefox are two afflicted sites, both with "DigiCert Global Root CA", is listed in /etc/ssl/certs/ca-certificates.crt
I too am seeing this on a regular basis. Chrome, OpenSSL and curl all accept the cert, and I've validated it's the same one Chrome is getting via SSLabs, so I know I'm not being MITMed. Always DigiCert, happening on two different computers.
It seems like if I restart Firefox half the time I get a session where it accepts the cert, half the time it won't, so the only solution is to keep restarting Firefox until it accepts the cert then don't close it for any reason.
This is constant problem since firefox 70.0-1 update couple of days ago. Duckduckgo doesn't work at all, reddit works on and off, I have run into several other sites that don't work or work every n-th load... Please fix this guys.
Not yet, I will if there is nothing more official in form of update that brings everything back to normal. I am trying to figure out if this is something few of us experience or everybody? I mean all of use have ff + those stock packages, right?
I'm having the exact same problem.
"DigiCert Global Root CA" is tripping firefox. Several websites stop working. If I reconnect and restart firefox, it seems to work fine. But it will inevitably break again.
Update: couple of updates of firefox-developer-edition later it now happens on both regular firefox and in developer edition. What is the proper way to raise this to maintainers attention, it makes any flavor of firefox pretty impossible to use? Is it possible to be localized problem so maintainers don't see it?
Applying the changes that @loqs recommended works for me. I also tried not applying the change to nss, because @progandy suggested that would have downsides, but it caused issues for me.
I can't confirm if there are any side effects of these changes or whether it's the right solution, but it does get Firefox working again.
Kindly do your due dilligence and report back to Mozilla regarding the FF slow down and performance issues so that they can improve it. Dont know if there is a firefox dev present in this forum to listen to your FF specific concern.
Still why not run FF ESR instead?
Developers editions are basically not meant for day to day use.
Of course you can run it, and volunteer to help the mozilla developers with reporting bugs to them.
I have installed firefox developer edition on my MX-Linux. When I tried to configure the live server of VS Code to run it as default, I failed. I followed this link to set up, but ultimately it is not working for me.
What I did after following the above mentioned link is to include this piece of line in the settings.json file after I entered config live server in the search bar "liveServer.settings.AdvanceCustomBrowserCmdLine": "/usr/share/applications/firefox-developer.desktop". However, it is not working out for me.
I figured out what I was missing. I added the path to the desktop entry of the firefox developer edition. Instead, what should have been done was to add the path of the actual application location. In my case, the path of the application was this /opt/firefox-dev/firefox(I saved the firefox developer edition in this directory).
I know that there are already some posts about developer editions of browsers such as Chrome and Firefox but I saw that people talk about a beta program. This doesn't seem to be the case with Firefox Developer Edition.
Most notably, Firefox Dev comes with additional development and debugging tools, some of them still experimental. That means more responsibility for the user and potentially a bigger attack surface since fresh features can be more likely to be vulnerable.
