I-Firefox Community Forum

Before I get to the heart of the matter I need to clarify something. My browser have updated to the new version two days ago. When I open it yesterday it did not restore my session, I checked resently closed windows but it was clean. I looked on the forums and found out that I can use old copies of the session to restore it, unfortunately the "previous.jsonlz4" had already been overwritten, but I found three upgrade.jsonlz4 which may be suitable for restoration, I saved it and others files in another folder. It is a list of files that I have saved: 1.previous.jsonlz4 2.recovery.baklz4 3.recovery.jsonlz4 4. upgrade.jsonlz4-2025.... 5. upgrade.jsonlz4-2025.... 6. upgrade.jsonlz4-2025.... Then the forum said that I need to select one of the appropriate files, rename it to sessionstore.jsonlz4 and replace the old one. The problem is that I can't find sessionstore.jsonlz4. It was said that it appears after closing the browser, but I couldn't find it. Now after this introduction I can move on to my questions. Is it possible that this file is now called differently and this method of recovery can still be implemented? And are there other ways to restore the session? I would be very grateful for help.

Hello! Today, suddenly, a video player disappeared on the Twitch streaming service (see screenshot), but the stream sound is playing. I tried clearing Firefox data and later reinstalled the browser completely - didn't fix the problem. I installed two versions (115.17.0esr and 115.23.1esr) because I thought the problem was an update. Both versions of the browser have a problem. In another browser, this problem is missing, Twitch is working! Operating system Windows 7 Pro SP1. Can you please tell me how to solve this problem?

I'm having problems with the browser when adding extensions. I received a response saying that my Firefox is out of date, which is a mistake because it's another browser. My problem is with the FlashPeak SlimBrowser browser, which has all the extensions expired and the browser also doesn't update.

Now I have another problem. I can't watch the stream on Twitch because the image doesn't load. I'm attaching the image for review.

I hope that this time you understand my problem and can get back to me with the necessary corrections.

Thank you.

DELL's new monitor, U3225QE, can be connected via Thunderbolt 4. I can display 120Hz and Edge and Chrome display without any problems. Only in Firefox there are some areas that should be displayed in white but are displayed in pink. By the way, when connected via HDMI 2.1, the display is 120Hz without any discoloration. If you turn on the dynamic refresh rate, the screen will go black every time you move the mouse. When it is OFF, Firefox browsing does not change color and can be used normally, I called Dell support and they told me, "That's probably a problem with Firefox." It would be helpful if Mozilla could address this issue.

I'm using Firefox in MacBook. When i'm accessing SharePoint site and any link related to SharePoint, i'm frequently get the prompt to sign in my Microsoft 365 account. i didn't face this issue when using Chrome or Edge. IT Team try to set conditional access from Microsoft to allow persistent token, it work well for Chrome but seems Firefox didn't take effect. Any help can guide me to reduce the frequent prompt to sign in?

Browser stopped showing all opened tabs across toolbar. Used to be able to see & toggle between several open tabs (websites) at the same time. Now browser only opens 1 bookmark tab & cannot even use backup button to see any previous tabs. Firefox 138..0.4

After a recent Firefox update my bookmarks went missing. Mozilla informs me that to recover them I need to go to about:profiles. There the "Launch profile in new browser" button is missing. Mozilla instructions advise me to click on it to begin the process to recover my missing bookmarks. If you know of a way to recover the missing button or know of another way I can recover my book marks I'd appreciate it. Thank you.

05/20/2025 twitch streams stopped working, image disappeared, sound is there. Also working videos that are on twitch, not streaming. In windows 10 everything works.

I am encountering an increasing number of sites that don't work with Firefox but do work with Chrome. I have tried turning off add-ins without success. Is there a way I can easily reset Firefox to its initial state and then return it back.

I'm using the vertical tabs feature. I also tried enabling the "Expand sidebar on hover" option, which minimizes the side bar, and only expands it when you hover on it.

Issue: I have a lot of open tabs, and I'm usually working with the ones at the bottom of the list. When the bar minimizes the scroll position resets back to the beginning. So, every time I want to select a tab, I have to scroll back down, which makes this feature very hard to use.

Expected behavior: After the vertical bar minimizes, and I hover again, it should keep the scroll position.

I am very used to switching tabs by using the keyboard so I usually do Ctrl+tab and I have it set to recent order (which makes sense to me because most of the time you switch back and forth between two or three tabs) to navigate between tabs. In some recent update, some tabs became unreachable by using this keyboard shortcut, as no more tabs are displayed nor do they appear when you reach the end of the list, forcing me to use the mouse to look for the tab (please see screenshot attached).

I was hoping this had a workaround or if it is a bug I would like to know how to report it.

Thank you!

Nicolas

Version: Firefox 138.0.3 (64-bit) on Ubuntu 24.04.

When browsing, the tabs and address bar get stuck somehow. Tabs can still be closed with "close other tabs", and new tabs can be opened by following URLs, but the tab component is fully stuck. Sometimes it fixes itself, but usually it requires browser restart.
