I had two Firefox windows open. One had 100+ tabs open, the other had around 5 open. Like a klutz I accidentally closed the window with the 100+ tabs open instead of the other window. Now when Firefox restarts it opens the version with the 5 tabs.  :-( I read about lost tabs in Firefox. I have found a file with the 100+ tabs in it. It is called: upgrade.jsonlz4-20221007134813. But what do I do next to restore Firefox to restart with the 100+ tabs version? Thanks.

I'm running version 118.02.2 (64-bit) of Firefox on Windows 12. I *always* have the 'Open previous windows and tabs' checked. Starting yesterday, Firefox opens with nothing other than a blank page. Luckily for me, this has happened in the past and I have a Bookmarks Menu folder with my default tabs saved. Even so, it's still frustrating.

I need pinned tabs to show their title, just like normal tabs. They currently only show an icon, but apart from the fact that in my case the icons are identical to one another so I can't know which one is which without hovering them, I'm more of a text person anyway.

So, how to make pinned tabs show their title?

Firefox has not been playing nice, and it is starting to worry me that if I continue to use it, my computer may suffer damage due to crashes.

It only seem to happen when I'm playing videos, such from YouTube and Twitch. It causes most of the time the tab to crash and require me to simply reload the page. There have been 2 times however that it has caused Windows OS to completely crash, requiring a restart. I have a picture of the error codes present, but one thing is shared between them. They all contain the reason EXCEPTION_ACCESS_VIOLATION_READ. This has pointed me to consider it to be the same issue. It may also be a issue with the new computer itself, or maybe something to do with the graphics card. I'll start with this first to see if it's something bigger or not.

I also hope that the trouble shooting data can also help, as I rather know how to fix this then be secretive with information that may help.

As as a final note, as of this moment, while being within safe mode/trouble shooting mode, no tabs have crashed yet. Hope this is a sign, but I'll keep it on just to make sure the videos aren't crashing anymore.

In Firefox 114.0.2, the tab foreground color for most NYTimes.com pages initially is black, but after an instant, the foreground color now becomes gray. The background color is a similar gray, so the tab symbol for the NYTimes (beginning with an ornate letter T) cannot be distinguished from the background. The NYTimes tab foreground color used to remain black.

For an example, go to https://www.nytimes.com/. The tab foreground colors for some NYTimes pages remain black; for example, go to https://help.nytimes.com/hc/en-us. I think this tab foreground color change began recently, less than a month ago. This problem does not occur for web sites other than the NYTimes. Restarting my computer does not help. This tab color problem does not occur in Edge or Chrome.

Thanks for any info

it's extremely annoying to have to stop what i'm doing and play "lets find the active tab" when i have tons of youtube videos qued in open tabs. in opera, the logic is there out of the box, but in firefox, it doesn't exist. why such logic wouldn't exist is beyond me, but i see this as an annoying problem that needs fixed. i want to simply glance up at the tabs and see which one is playing without having to spend time digging through the open tabs to find the one that's playing or having to freakin memorize which one it was i don't have time for that.

i followed the guide in this thread: https://support.mozilla.org/en-US/questions/1291998 i did exactly everything as instructed but it did absolutely nothing, no change at all.

I need to shrink the size of my tabs, which remains constant no matter how many are open. If I have four open, I get the "+" for a new tab at the end of the tab bar. If there are five open, the tabs consume the entire width of the browser window and the "+" sign disappears. It is not found in the "customize toolbar" menu. I have tried restoring tool bar defaults and changing the uidensity to 1, but neither change shrinks the size of the tabs or gives me the "+" option.

What do I need to do to get back to the way it used to work?

Within the last hour or so, I needed to close Firefox while installing an app (the setup was recommending to close all Windows programs).

Had 8 windows open.

Right-clicked on the Taskbar Firefox icon, then selected the option "close all windows" - it proceeds to close each window consecutively, asking me each time for manual confirmation whether to close this window with x tabs in it - and I just confirm each time.


So then after that setup is completed, I open Firefox again - the last closed window is restored (as per the settings);

then I click on History, "recently closed windows", and.... there's only 2 windows on that list. I restore those 2, and then the list is empty - nothing more to restore.


So if I had restarted the PC, it would've just restored the 8 windows upon reopening Firefox, as usual - but since I opted to just close Firefox like this, "close all windows", I just lost 5 windows.


So could anything be done here?

Something in the files? Maybe the C:\Users[user]\AppData\Roaming\Mozilla\Firefox\Profiles\4qu1kfr9.default-release\sessionstore-backups path? There's a file called "previous.jsonlz4" in there, something I could do with that one?

Or something else?

Any help would be appreciated!

"Container Tabs" are unavailable in Firefox on my employer's corporate PC. The "Enable Container Tabs" option is missing in the Tab section in Settings. There is a notification "Your browser is being managed by your organization." Thus, the lack of container tabs may be due to corporate policy. However, I don't see anything on the Active Policies page except one irrelevant record: "InstallAddonsPermission Default false." Additionally, "Container Tabs" are unavailable only in Firefox. Nightly has them. But, Nightly is not officially supported by my company. I have tested several corporate PC and different versions of Firefox and Nightly. Is it a weird Firefox bug or something else?

Hello at Mozilla Support,

I'm having this issue where sometimes, when I double-click to download a link or open a downloads item, it opens the same bookmark page instead. This is the page, and not sure if it's alphabetical, since this pages starts with an 'a' "https://authorspublish.com/#optin" Wondering how I can get this to stop changing the page I am on and opening the bookmark.

Thanks, Sonya

This isn't a constant issue for me, but occasionally the browser will suddenly break such that when I switch tabs, nothing actually updates until I do something like restore/maximise the window. I can still interact with the page itself, but whether using the mouse or keyboard shortcuts, changing, opening, or closing tabs, or even typing in the navigation bar, won't do anything until I resize the window again. I haven't been able to figure out any pattern to when this state triggers, but after it does, it doesn't clear up without closing and reopening the browser. I have recorded a video showing this behavior but I am unable to upload it here, and still images would not properly convey the issue.

Opening new tab via right-click on other tabs doesn't put cursor focus in URL bar

If you have multiple tabs open and you hit Ctrl-T to open a new one, it opens it at the end of the tabs, and the cursor focus moves to the URL bar so you can start typing in an address/search.

If you right-click on any of those tabs, it opens a new tab to the right of that tab, instead of at the end (which is what I want, as right-clicking on a specific one to open a new tab, to me, means you are linking those tabs in layout and want them together) BUT the cursor focus DOES NOT move to the URL bar.

This seems pretty counter-intuitive, and means that so many times I right-click, Open New Tab, and start typing a URL and then see that I have to stop typing, click in the URL bar, and start typing all over again.

Is there an about:config to force the focus to the URL bar, or is this a bug? If there's no setting for this, I would definitely consider this a bug because you have 2 different behaviors for New Tabs.

I have custom URL's set when opening my homepage. For the last few weeks, Firefox has been opening tabs from the last session. I've checked the URL's and they are correct in the settings but for some reason they're not loading properly.

These are the correct URL's in the setting page. https://www.etsy.com/your/shops/UiJewelryMaui/tools/listings/state:sold_out,sort:sold_out_date,stats:true|https://www.etsy.com/messages?ref=seller-platform-mcnav|https://www.shopify.com/|https://maui.clareityiam.net/idp/login|https://outlook.office.com/mail/|https://calendar.google.com/calendar/u/0/r?pli=1|https://www.microsoft365.com/?auth=2|https://www.canva.com/|https://hawaii.infinitecampus.org/campus/portal/parents/hawaii.jsp|https://mauinews.org/pub920.htm|https://www.mauicounty.gov/Bids.aspx?CatID=19|https://hiepro.ehawaii.gov/vendor-dashboard.html|https://us2.admin.mailchimp.com/campaigns?ref=plums_nav&_ga=2.43380451.756894218.1698551103-1299448220.1698551096#f_bucket:recent;t:campaigns-list|https://hawaiicovid19.com/

However, the pages that load at start up are not these URL's, instead they're opening with the ones in the photo I provided. How do I fix this or do I need to select a different default browser?
