when playing a video on youtube a mute button should appear when hovering over the tab when language is hebrew, this sign appears always, being on top of the website icon

Every day I have to work and use my pinned tabs. But now, they disappear every time Firefox restarts, notwithstanding that your settings indicated Firefox will reopen all tabs on the next session. Why? Where I live there are blackouts every day, especially during the night. So I have to close all my programs, turn off my computer, and restart it early in the morning in order to work. Please turn back to reopen pinned tabs every time Firefox reopens!

bold textI get this message Gah! your tab just crashed It happens after I have already brought a site up then want to bring a 2nd or 3rd tab up

Gah. Your tab just crashed. We can help! Choose Restore This Tab to reload the page.

That is what I keep getting.

So some website didn't work for me and I pressed "forget" button thinking it only removes history from a particular website (no). That's it - EVERYTHING COLLAPSED, session is lost, all tabs gone. Trying to restore from "sessionstore.backup" - no result. Trying from synced - oh sure CRAP IS TURNED OFF like always for NO reason

Thanks a lot, douchebag morons. Hope you all die + anyone suggesting to copy "sessionrestore" gets testicle/boob cancer + anyone suggesting to turn sync on can eat my crap

Hello.

Since some time (few months, can't really say when this started happening), the middle mouse button click on a tab stopped working as before. I will describe the expected behavior and how it (still) works on the same computer with a different browser (Chrome):

1. Hover over a tab 2. Middle-click closes a tab 3. Tabs right to the closed one move left 4. Middle-click closes a tab 5. Steps 2-4 may be repeated unless there are no tabs opened 6. Leaving the tabs bar (if any left opened) will now rearrange the remaining tabs (increase their width, etc)

Now, here is the not so great behavior I am facing in Firefox: 1. Hover over a tab 2. Middle-click closes a tab 3. Tabs right to the closed one move left 4. Middle-click rearranges the remaining tabs (increase their width, etc) 5. Middle-click closes a tab 6. Steps 2-5 may be repeated unless there are no tabs opened 7. Leaving the tabs bar (if any left opened) will now rearrange the remaining tabs (increase their width, etc), if you have left at last step 3

See, there is this extra step #4 which is really bugging me enough to actually come and ask for a support.

I am on Ubuntu 20.04, using latest version of Firefox (to date).

Many thanks!

Subject: Report of Shortcut Image Swap Issue in Firefox

Dear Firefox Support Team,

The issue I am facing relates to the shortcut images associated with different websites and web applications pinned on Firefox’s New Tab page and bookmarks bar. Instead of displaying the correct icons for their respective websites, these shortcuts are randomly swapping their images with one another.

Steps to Reproduce:

1. Open Firefox.

2. Pin multiple websites to the Shortcuts Section, each with its unique icon.

3. Over time (minutes, hours, or days), observe that the shortcut images have switched places with other shortcuts, leading to a mismatch between the icons and the associated websites.

This issue seems to occur without any user intervention and appears entirely random in its behavior.

The ongoing issue with shortcut image swaps is perplexing and disrupts my browsing experience as I rely on these visual cues for quick and efficient navigation.

Last October my sessions were gone after a Firefox Update. I asked for help here: https://support.mozilla.org/sv/questions/1394685 and eventually got kind help from @cor-el (that unfortunately wasn't skilled enough to understand) and from @RayGibson57. But by then, my life was in a flurry and I didn't have time to try the advice. And so, after a while I had, with some effort, gathered many of the old tabs back again, and built up new sessions.

This Monday I was trying to internet while having high fever (something people should never do :o ). I left three blank windows open when I shut down the computer, and next morning those three were the only ones Firefox wanted to remember.

(I still find this change frustrating, bordering on infuriating: what happened to "Choose how many old sessions you want Firefox to remember", I think the maximum was ten?)

Now the fevers left and I went to those answers to try. That Q/A was archived though, so I'm starting again here, from as far as I got following King Rays instructions. They were:

1. Open the application menu (3 horizontal lines) next to the address bar.
2. Click on Help -> More troubleshooting information.
3. With that page open, find Profile Folder and click on Open Folder. That's how you get to the folder with backup files in it.
4. Set computer up to see all the extensions & system files. By default, the extensions don't show up (.jsonlz4 is an extension).
5. I found an older file in that sessionstore-backups folder and copied it one level back to the main profile folder.
6. Renamed the sessionstore.jsonlz4 to sessionstore.jsonlz4.old and the file I copied, I renamed to sessionstore.jsonlz4.
7. Opened Firefox and that missing window was in the history so I could open it.
8. Don't make any typos here, because Firefox won't find the files it needs to open.

I got as far as finding the Profile folder and the sessionstore-backups folder.

But I cant find any jsonlz4 file called "sessionstore". Only a "sessionsCheckpoints" and that one is a json file, and the date modified is today.

See screenshots please!

Can anyone talk me trough this like Im a grandmother from Sweden with extremely limited coding & tech skills (which is what I am)?

This morning i restarted firefox and it only opened 3 of the 4 windows i closed yesterday. I've just read about the limit of 3 windows reopened after closing, but now i can't restore the 4th one (it was the manin window with many tabs opened). In history i can't click on "Recently closed windows" and ctrl-shift-n doesn't work. I made a backup of my profile outside of the usual firefox folder. Is there something i can do to restore the 4th windows? I don't mind losing the other windows, but i need to recover the main one. I also tried this tool https://www.jeffersonscher.com/ffu/scrounger.html but it doesn't seem to work with the files inside startupCache.

When I open a new tab, i would like the page to be in focus and not the urlbar. This is what i used to have in my mozilla.cfg: ``` // Auto focus new tab content try {

 Cu.import("resource://gre/modules/Services.jsm");
 Cu.import("resource:///modules/BrowserWindowTracker.jsm");

 Services.obs.addObserver((event) => {
   window = BrowserWindowTracker.getTopWindow();
   window.gBrowser.selectedBrowser.focus();
 }, "browser-open-newtab-start");

} catch(e) { Cu.reportError(e); } ``` This worked until the last update. What solutions are there?

This started a few hours ago and I can't get it to stop. I've tried restarting Firefox, restarting my computer, reducing the tabs I have open. It basically freezes up and then every single tab has the loading icon.

It doesn't appear to be crashing and restarting because I don't see the windows disappear at any time.

I've tried looking online but I can't find anybody else encountering this.

I have it so it normally and always have opened tabs I am using whenever I reopen Firefox. But from today, it doesn't work. I checked in settings, it is on under Startup "Open previous windows and tabs", but it doesn't do so. But if I click CTRL+SHIFT+T it reopens all my windows tabs, but in another window. It's like Firefox thinks my main Startup is that blank site, where I left of last time, and doesn't update even that on opening all tabs, it opens a completely new window instead. Very weird behaviour. Any way I can fix this? It is really frustrating.

Default browser is Firefox. When it is not already open and I click a link in email or Messages it open Google.com. It used to go directly to email link address. I am using Macbook Pro. I just downloaded Firefox 117.0 Was there a change in setup or Firefox 117.0?

I opened up my browser and all my active tabs which I have had for months are gone. I tried to go to recently closed tabs in history and it doesn't allow me to open. All are not available. Help!!

if i have for example 4 tabs open i will also have 4 windows that all share the same tabs. i have tried using "about:config" and inputting "browser.tabs.allowTabDetach" and setting it to false and it doesnt help. what can i do to get opening a new tab to stay on the same window
