Hello,

When FF on my Windows 10 machine crashed FF asked if I wanted to refresh FF. I said yes, and FF reopened as usual with all my tabs. After I closed and reopened FF the next time, it reopened without any of my tabs. I then discovered that FF had unchecked the “Startup Open previous windows and tabs” box, which I had previously religiously monitored to be sure it was checked. So I lost all my previous tabs.

In my sessionstore-backups folder I found the file upgrade.jsonlz4-20 as last in a list of three more recent file names. I then dropped the file upgrade.jsonlz4-20 in the scrounger tool on this site: https://www.jeffersonscher.com/ffu/scrounger.html. It expanded in the big window, and when I clicked on Save uncompressed JSON as text, I see all the URLs run together in a text file.

How can I use this information to recover my tabs, please? If so, how? Or is there a better way to use the Scrounger – or another – tool?

Otherwise if I delete the three more recent file names in the list above the upgrade.jsonlz4-20 file, and restart FF will I recover the missing tabs? If so would I the check or uncheck the Startup Open previous windows and tabs box?

Lastly, can I restore my missing tabs using Windows’ “System restore” tool from 3 days before the crash?

Many thanks for any help!

I have a website that has MP4 video in a HTML5 video player, with subtitles done in the WebVTT format (*.vtt). I just noticed that, when testing my pages locally on my C drive, the subtitles no longer appear on the movies. They do appear on the website (thankfully). Does this mean that lately Firefox has dropped support for local VTT files? Chrome has always ignored local VTTs, for some reason, which is why - until now - I used Firefox to test subtitles off the C drive. Note: If I link the local page to the VTT file on my website, subtitles still do not appear in Firefox. It could be something else, of course, so just need to know if VTTs are now unloadable locally in FF.

Last year someone asked about 2 Firefox for Android applications; I just had two different copies of Firefox installed on my Win 10 laptop (one in an attempt by Microsoft to upgrade to Win 11) where all my data was in the old app named 'Mozilla Firefox') while the newly installed app was just 'Firefox' and had none of my data. I did not attempt that new install, it seems Microsoft did ?? They also mentioned wanting to redirect the new Firefox to specific Domain Name Service servers, rather than the traditional server addresses provided by the local network. Anyone know what's going on?

Hi I'm using Firefox to open PDF files from a network directory. The reason is that it's probably the best PDF manager I can find.

  • What I wanted to do was have an option to open the file in a native viewer such as Adobe, this way look at 2 parts of the document at the same time.

At the same time keep it in Firefox.

Is there a setting to do this or an add-on. The add-ons I've seen are meant to open directly to Adobe from a web link I think.

Hi, I've just spent all day trying to follow all the different suggestions here regarding these issues. Adding all sorts of things to the userChrome CSS but 95% of the suggestions have no effect at all [I'm seriously non-technical, so I have no idea if I'm doing it correctly though...probably not] The only thing that I can change is the Tab Height...nothing else changes regardless of what numbers I put in there. The only way I've been able to make the Bookmarks folders usable at all is to enable Compact mode via about:config. But that actually makes it way too compact now...from one extreme to the other. At least it's usable now...so not the end of the world, but the right click menu still has way too much space between every entry [Compact mode made no difference to that at all]. I don't know how to make a screenshot of those menus :) so I took a couple of pics of the screen...can someone please show me what to add to the CSS file to make these ridiculously big spaces between the menu items way smaller...like they used to be before this Proton came in? I tried tons of things that people said to add to the CSS to fix this menu spacing thing but none of them changed anything. I'll include the CSS file that I have below. Thanks a lot

ps: for some reason the pics always come out sideways here

Using Firefox on desktop, Windows 11. I am a long term Firefox fan/user.

My problem is I cannot find anywhere an easy method to add a shortcut on my Home Screen (which has now been a FF feature for some considerable time).

I am sure there was something available to do this in a prior version some time back. If I search the internet, I only come across articles describing how to do it on Firefox Android.

I know I can manually edit a box on the Home Screen to create what I need.

Sometimes new web sites that I visit appear in the boxes and I can then pin them in place - but the behavior around this is very erratic and unreliable - seems like random chance for an icon to appear on the home screen for a newly visited site. If this was more consistent, I could work with that.

BUT - where is the **intuitive** option??!!

I should be able to right-click on a tab and select "Add to Home Screen".

As simple as that.

Or drag and drop a link, or tab to the home screen - but this just opens the link. I have tried everything obvious that I can think of.

Anyone?

Many thanks :)

I managed to restore the single-spacing for bookmarks, kept a prior version of FF, and fought off nags to update every time I opened FF . . . until now when I was tricked into "allowing this app to make updates to your PC". It wasn't the usual nag button and I thought it was some kind of simple bug fix, but no, I was "upgraded" to v. 100.0.2 and my bookmark spacing fix was overwritten. Furious isn't strong enough to describe my reaction. All this time, and all the other complaints, yet I find no way to decrease the excessive spacing between bookmarks. I understand that this design may be better for those who use a finger on their screens, but what about us mouse-pointer users? Why are we so disrespected? What can I do to decrease the space between bookmarks?

Random videos will not load following 100.0.2 install.

These symptoms started @ May 21. (See attached file "Recently installed")

This problem is 100% reproducible at: https://www.reddit.com/r/CatastrophicFailure/

Lenovo Thinkpad x140e Windows 7 (all updates installed) Mozilla 100.2.8174

Scrolling down the Reddit page, videos will auto-play when exposed, and stop when scrolled past.

A video not loading/playing will occur on different posts/videos, but will ALWAYS occur. Once this occurs some previously exposed / played videos, when scrolling up, will play when exposed again, and some will not.

This will also randomly occur on Youtube (also observed on Twitter a few times) when multiple tabs are open. Sometimes closing other open tabs corrects the problem. Other times closing Firefox and relaunching is required and is 100% effective.

I have additional diag data / Inspector log files and page source if needed.

Thank you in advance for your help and consideration. - LudditePro
