So, whenever my Firefox updates, it seems that it completely wipes my history, and deletes all my tabs, despite it being set to "re-open previous tabs on launch".

This has happened multiple times now and is really not fun. Do I just need to make bookmark folders for everything I do? Because having everything randomly delete itself, without even a session restore in the backups folder of my firefox profile, isn't ideal.

I do have a sessionstore error for this, where I presume the problem is laid out.

I have my settings set to open PDF files in Adobe Acrobat, but the latest version of Firefox has started opening them in their own viewer, which is NOT near as useful, and I then have to download it to open in Acrobat like I used to do. Why? Is there any way to fix it back?

new computer. log into firefox, nothing is saved. pin an app, come back and it's gone. have to log into the app EVERY TIME. have to log into firefox too. why is it not saving anything???

Why the h377 did firefox change the screen shot tool by removing it from the address bar AND delete the center search bar, along with changing the location of all my recent web visit from the along the bottom of the screen? This is annoying and unhelpful to pc users, I need these functions back like they were in order to us your site on my pc. I donot and will never use firefox on my phone. If these functions are gone, then I will have leave as well. Either that or remove the update from my pc and cease ALL further updates.

Racenet is a formguide put out by News Corp and subsribed to by mug punters like me but i am unable to download it with the message 403 ERROR the request could not be satisfiedbold text

When I bookmark a website and select edit, it does not show my created bookmarks to save too, nor can I move existing bookmarks to created folders, why not? I have to create a folder, then select all my existing important bookmarks and save them to the created folder. I can not later add any saved bookmarks to the created folder, why not? The Beta version has the same issue. Please make a change to allow for bookmark saving or moving to created folders. Thank you.

After the last update, Firefox won't open. Instead, I get this message:

"Firefox is already running but is not responding. The old Firefox process must be closed to open a new window."

I have closed it within the error message but the error message comes back each time I try to open Firefox.

Please help, Deb

Hello,

I'm troubleshooting a Firefox Desktop issue that I haven't been able to reproduce consistently in other browsers.

I use a browser-based precious metal calculator that performs calculations instantly using JavaScript. The page loads correctly, but after changing several input values and navigating between tabs, Firefox occasionally continues displaying an older calculated result until I perform a hard refresh (Ctrl + F5).

I've been able to reproduce the issue consistently using this scrap calculator scrap calculator. The page loads normally, but Firefox sometimes continues displaying an older calculated value until a hard refresh is performed.

The page itself loads normally, and there are no visible JavaScript errors in the Browser Console. However, the displayed value sometimes does not update immediately after changing the weight or purity inputs.

So far I have tested:

• Firefox Troubleshoot Mode
• Disabled all extensions
• Cleared cache and cookies
• Tested a new Firefox profile
• Disabled Enhanced Tracking Protection for the site

The issue appears only in Firefox Desktop. Chrome and Edge update the calculation instantly under the same conditions.

Has anyone encountered similar behavior involving JavaScript-driven calculations, form inputs, or page caching in Firefox?

Are there specific Firefox settings or diagnostic tools I should check to determine whether this is related to caching, page state restoration, or another browser feature?

Thank you for any guidance.

It seems to be related to video playback but not sure. It was happening while a video was playing full screen, and also after stopping playing/hiding a non-full-screen video.

To catch the issue had to screen record at 240fps. I used Nvidia Overlay to record the issue, but was happening before the overlay was even enabled.

Disabled all addons, made no difference. HW acceleration on or off, still happened.

I tried turning on logs, and this always seemed to show up with the flash: ``` 2026-08-09 06:19:44.048000 UTC - [Parent 8388: Main Thread]: D/Widget GetWorkspaceId - calling AsyncUpdateWorkspaceID() 2026-08-09 06:19:44.048000 UTC - [Parent 8388: BackgroundThreadPool #276]: D/Widget calling GetWindowDesktopId 2026-08-09 06:19:44.048000 UTC - [Parent 8388: Main Thread]: D/Widget GetWorkspaceId - calling AsyncUpdateWorkspaceID() 2026-08-09 06:19:44.048000 UTC - [Parent 8388: Main Thread]: D/Widget GetWorkspaceId - calling AsyncUpdateWorkspaceID() 2026-08-09 06:19:44.048000 UTC - [Parent 8388: BackgroundThreadPool #276]: D/Widget called GetWindowDesktopId, hr=00000000 2026-08-09 06:19:44.048000 UTC - [Parent 8388: BackgroundThreadPool #276]: D/Widget calling GetWindowDesktopId 2026-08-09 06:19:44.048000 UTC - [Parent 8388: BackgroundThreadPool #276]: D/Widget called GetWindowDesktopId, hr=00000000 2026-08-09 06:19:44.048000 UTC - [Parent 8388: BackgroundThreadPool #276]: D/Widget calling GetWindowDesktopId 2026-08-09 06:19:44.048000 UTC - [Parent 8388: BackgroundThreadPool #276]: D/Widget called GetWindowDesktopId, hr=00000000 ```
