I lost all my tabs groups with the the update to release date for Firefox 138.0.4 on the 2025-05-19. Tab groups are still configured but my sessionstore.js is missing. I notice that there is a backup in Session-store backups dated the 2025-05-19 so I presume the tabs groups are still stored there. Can anybody suggest how to get the tab functionality back? I'm hesitant to just restore the sessionstore.js -- the actual tab group functionality is gone. I can't even recreate the groups.

My locahost React JS development environment with Vite stopped working after the last update. When I run the development server on "http://localhost:5173/", the page never resolves. It work fine on my other machine. Is there some security setting prevent the page to load?

I have what someone else called "gibberish" at the beginning of my e-mails. I do not wish to have it so how do I get rid of it?

It includes the following topics: X-Mozilla-Status X-Mozilla-Status2 Return -Path Recived X-SW-ORIG-RCPT

and  much more

I often keep hard copies of my emails and do not wish to print the gibberish. I never used to get this gibberish and why is it now being sent?

I just updated my Firefox app and it rearranged all my bookmarks. I would love to go in and resort them back to how they were before, but the only options I have on mobile are automatic sorting of alphabetical or chronological. I don't know if the manual sorting option was removed, but if it hasn't I'd like to know how to acess it. Thank you!

I would like to be able to view the names of tabs and the address bar. I am able to adjust the page views and all is well there. I do not want to use stronger glasses just to view the tabs and address bar and then switch to another strength of reading glasses.

Hello, Until recently, I was able to double tap the browser bar and have the window expand to fill the screen just short of "full screen" mode so I could still see the menu/task bar. I remember I did need to adjust settings for this somewhere but can no longer figure it out now that it is not functioning to this spec any more.

I did check about:config to see if "apz.allow_double_tap_zooming" was set to TRUE and it is, by following this suggestion below:

Is there a setting that I am missing that allows me to see parts of two months simultaneously? As an example; May 2025 ends on a Friday and I have an event which straddles the two months. Unless I have missed a setting somewhere, I am forced to toggle back and forth between the months to see how the timelines are laid out. Perhaps a minor irritant, but one which I can only recall running into in the Thunderbird calendar.

If there is a setting I am missing, please point my blind eyes to it. If not, this could be a nice improvement. Toggle or no toggle.

Thanks all.

I have a program which I use exclusively on Firefox and until a few days ago I could open the rtf files which I downloaded on MS Word. Suddenly they won't open. I was told to go to the settings >In Firefox Settings>General, under the “Files and Applications” section, be sure that RTF files are set to “Open in Word” There is no rtf listed there as a file type. Did something get changed recently? This is a massive problem for me. I really hope you can help. Thank you

Hello,

I’ve noticed that Firefox does not show the translation icon in the toolbar for a webpage, even though the page is in English. When I manually go to "Application Menu" → "Translate Page…", I receive the message: "Translation is not available for this page - Sorry, this language is not yet supported." However, if I click on "Change source language" and manually set it to English, the translation works correctly. It seems like Firefox is not detecting the language of the page automatically, and as a result, the translation feature does not appear unless I manually intervene. The issue occurred on this page: "https://mantisbt.org/docs/master/en-US/Developers_Guide/html-desktop/#dev.contrib.submit.before".

I also looked for a way to report this issue, but I only found a form for reporting incorrectly translated words here: "https://docs.google.com/forms/d/e/1FAIpQLSdoRWnsHX6vVnGIRyLi4Kl-p0GrmeVIioqWsTz3aVTRfLScng/viewform". There doesn't seem to be an option to report entire sites where the translation does not work at all.

I'm using: Firefox Desktop 138.0.4 (64 bit) on Windows 10 22H2. Thanks for your help.

In detail:

1. Numbered list item showing something went wrong page when I am trying to login from (about:preferences#sync);

Note that:

1. Numbered list item cookie allowed;
2. Numbered list item using newest version;
3. Numbered list item protection set to standard;
4. Numbered list item tried to reinstall firefox

Each time I shut my Mac off and the next day open it up again, Firefox opens up and there are NO bookmarks on the left side. So I have to do the Command B to get them back up. I have neverf had to do this until recently??????

I use an iMac and Macbook Pro. Autofill that used to work is no longer working on both of these when I go to USPS.com and sign up for updates on packages. It use to fill in my name on the top line and on the bottom line, it would fill in my email.

What can I do to get this feature back? It stopped working around the beginning of 2025.

Thank you, Martha.

I'm trying to have Google.ca as my homepage, but Firefox won't let me. It keep reverting back to Google.com Please help. Claude Hamel [edited] @gmail.com

Hello. My untouched hyperlinks changed their color from darker blue to lighter. Visited hyperlinks remain as they always were, as far as I can tell.

This video has the color scheme I'm used to: https://youtu.be/V7gfuh-dRHM?si=uS3_PlVUdhu-48Kj

My colors changed, seemingly randomly, to the attached screenshot

Another thing worth mentioning is that if I open a new private window, the colors are what I'm used to.

What can I do to revert the change? How could this happen?
