Download Helper For Firefox

[Mirtha Shikles]

Iam restarting FF. I am on 76 and the install is for 77. A window pops up asking for my credentials to install a new helper tool. I don't recall seeing this before and it looks a lot like Oracle's Java installer that tries to install a bunch of crud. In that case cancel continues with the Java install. In this case, Cancel stops the FF upgrade.

I took the advice to delete the MacOs App and reinstall the latest (77.0.1). This installation went fine without further prompts. I suspect that the "helper tool" ended up being installed but at least it did not require my password.

Before the delete and reinstall, I had user ownership on Firefox.app and below from what I could see and Group was 600. After app delete and reinstall I see that the group ownership is now "Admin" on Firefox.app. 600 is my personal GID, though I am also a member of Admin. I "think" I installed Firefox originally before the Catalina update but I am fairly certain that I have had at least one Firefox update after the Catalina upgrade. It is possible that the same helper prompt came up then and I went ahead instead of questioning it.

Then cast a critical eye over the list below that heading. Any extensions Firefox installs for built-in features are hidden from this page, so everything listed here is your choice (and your responsibility) to manage. Anything suspicious or that you just do not remember installing or why? If in doubt, disable (or remove). For your privacy and security, don't let mystery programs linger here.

It is misleading that the pop up says that Firefox wants to install the helper tool. It would be much more helpful if the pop up indicated that FF is being asked to install the helper tool, or even better what extension specifically, if that it is in fact due to an extension update.

It happens if I click "Restart to update Firefox" in firefox. I would guess that it is a legit thing from firefox, but, I've never heard of a "helper tool" before. I would rather know what a helper tool is before I allow one to install.

I'm a staunch Safari user (at least on my Mac) so my suggestion to you is delete the FireFox app, go to another browser and download a clean instance of the most recent version from Mozilla.org instead of allowing this one to update.

The venerable Firefox Plugin "Video Download Helper" has been a mainstay of internet video downloading for years. However since I upgraded to Ubuntu 22.04 it can not ever find the "Companion App" it needs to work.

But then in the plugin does not work (tried restarting firefox, reinstalling plugin, etc.). If you go into the plugin configuration, there's a Recheck button in the "Verifying Companion App..." section, but clicking it does not seem to do anything.

For me, the installation of firefox beta version via snap was the solution ( -for-testing-native-messaging-support-in-the-firefox-snap/29759).

In this version, you get native massaging support inside the firefox snap package.

I found over the weekend that there is also a "Download with Web Browser" option that can work instead of using the companion app. Just proceed as normal, when the download begins, a dialogue window will popup prompting you to download the helper. But next to this is a button marked "Download with Web Browser" (or suchlike). Just click that.

I managed to get the VDH supplement app working. The path was simple: I followed the instructions provided by VDH on the page with the download of the supplementary app, however I didn't install the .deb version (I didn't know how to start it) but the tar.gz "version".

Basically I followed the download instructions on different linux distributions, the two command lines you find on the site do all the rest.The file was downloaded in the Download folder and then after the first command it is extracted in the Home and becomes executable when necessary, the second command I don't know but execute it.

I have a problem with a jQuery UI 1.7.2 sortable list in Firefox 3.6, IE7-8 work fine. When I'm scrolled down a bit, the helper element seems to have an offset of the same height that I'mscrolled down from the mouse pointer which makes it impossible to see which item you originally started dragging.How do I fix this or work around the issue? If there is no fix what is a really good alternative drag-able plugin?

If you want to prevent browser sniffing, the CSS only solution is to set the ul or a container style to overflow: auto. If you look at the source through firebug, it's the way jQuery does it in their example.

I was seeing this issue and was able to solve it by removing the css rule position:relative from one of the containing divs on my page. See also: -offset-when-element-is-dragged-and-page-scrolled-down-ff

You also need to account for the fact this is specific to firefox, here is the snippet I'm using - I got directed the right way from Harris' solution. I encountered this problem w/o using the helper when the sortable was in a relatively positioned container.

Basically, you need to listen for the sortable's "start" event to add the browser's current scrollTop() value to the helper's position, and then you need to listen for the sortable's "beforeStop" event, to remove that offset before the item is officially placed back into the list at its new position.

For future readersI ran into a similar problem where the helper element has an offset when dragging inside the scrolled div of a bootstrap dialog. When releasing the dragged object, the animation sends the dragged helper element towards it's new position without considering the scrolled portion of the page, which gives a confusing feedback to users.

Setting overflow: auto makes Firefox start the drag with the element under the pointer, but it also prevents autoscroll from working properly. You can see that right in the jQuery Sortable example, if you make the window small enough that scrolling is needed.

I had overflow: scroll on the html tag, but even removing that and (I think) all the relative containing elements didn't totally solve the problem (meaning the drag starts correctly and autoscroll works). I also tried a mozilla-sniffing patch to _findRelativeOffset (I think that was it), but it didn't help.

What did help for my use case was just dragging with a clone (helper: 'clone' in the draggable constructor). To make it look like the clone wasn't there, I added start and stop methods that just set the visibilty to hidden and then back.

NPAPI plugin support has largely been discontinued by browser manufacturers. Functionality that was previously installed with NPAPI plugins is now handled by helper applications, which are installed on the user's machine, and handled with protocol handlers. We install an Endpoint Check application and a Network Access application. These clients can be downloaded from the APM administration console and can be distributed for download by users, installed by group policy, or installed by device management solutions.

This release supports Linux versions that comply with the freedesktop specification. On Debian Linux, the f5epi and f5vpn packages require the user to install a new version of QT (minimum version 5.5) that doesn't exist in the stable repository.

**Windows Protected Workspace and Windows Cache and Session Control access policy items are not supported with the F5 Helper Applications in Chrome, Firefox, or Edge browsers. Use Internet Explorer to support these features on Windows 7 and Windows 8.1. Protected Workspace is not supported on Windows 10.

This seems to be a common misunderstanding. Helper Applications are only used if neither Mozilla itselfnor a plugin can handle a specific file. Only in that case will Mozillause an application chosen in Preferences/Helper Applications to open afile.

Sometimes, Mozilla tries to load a URI that it can't display,say a .zip file. When that happens, Mozilla consults the HelperApplication preferences to find out what it should do. There areseveral possibilities: Mozilla can open the file with the (system-wide)default application, it can open it with a user-specified application,or it can save it to disk.
