After clicking OK the TWc wiki did not load anymore. Comparing the wikis before and after saving showed differences at 15 places (only the first and last change important); see the P.S.
Thereafter I did some tests with a Minimal Test Case (empty TWc 2.8.1; closing/restarting FF in between tests)
Test 1: standard FF (all add-ons enabled) => error message after saving/refreshing but wiki reloads normally
Test 2: standard FF (all add-ons disabled except File Backups) => error message after saving/refreshing but wiki reloads normally
Test 3: standard FF (reinstalled FB, other add-ons disabled) => error message after saving/refreshing but wiki reloads normally
Test 4: FF dev (all add-ons disabled except File Backups) => error message after saving/refreshing but wiki reloads normally
Test 5: empty 2.9.2 standard FF (all add-ons disabled except File Backups) => error message after saving/refreshing but wiki reloads normally
Comparing the TWc wikis before and after saving showes differences at 3 places:
empty 281 before save:

<body onload="main();" onunload="if(window.unload) unload();">
<div id="tiddlyfox-message-box" style="display: none;" data-message-box-creator="file-backups"></div>
15) The added div at the end:
<div id="tiddlyfox-message-box" style="display: none;" data-message-box-creator="file-backups"></div>
Removing the div and adding the deleted code (in a text editor) created a working TWc again.
I think I did find the real problem and fixed it. ... There is a new beta version. Please try it: https://github.com/pmario/file-backups/issues/28#issuecomment-525451252
Hi Mario,I think I did find the real problem and fixed it. ... There is a new beta version. Please try it: https://github.com/pmario/file-backups/issues/28#issuecomment-525451252Bingo! Version 0.3.10 works for me.
Since it was quiet in the groups about saving TWc with File Backups I thought: 'Am I the only one? Something wrong with my system?'
But I see now that at Github the same behavior was reported (and also that it was still working under Windows 10).
The following tests (added new tiddler, saved and reloaded) were all succesful for:
Linux Mint 19.2
Firefox 68.02
- various TW5s
- empty 2.8.1
- empty 2.9.2
- heavily modified TWc 2.8.1
- heavily modified TWc upgraded to 2.9.2
Thanks a lot.
As for your initial problem, try to disable security.fileuri.strict_origin_policy option in your FF's about:config.
I suspect that the culprit is recreateOriginal which doesn't take into account some aspects of saver plugins;
current Timimi implementation has a similar issue, which I haven't reproduced yet but I'll check my guess too.
you may also be interested in Timimi for TWC, it's quite handy with FF, although the Timimi's advanced backups system is not supported yet for TWC.
