I had a similar problem last year when an auto update came through. After several suggestions didn't help I opted to reinstall a previous version and upgrade that. Now it's back again with the v94 update.

I've disabled ALL extensions. No help. Themes don't seem to make a difference. However, when I went to about:config and entered "toolkit.legacyUserProfileCustomizations.stylesheets" to make it true to allow chrome.css files to work it began immediately. Reset it to false and "X"s are back. Set config to TRUE and it screws up the "X"s. Again, all this is with all extensions off.

I hate the transparency of the tabs and menu bars so I need to set .css files. How else can I do it?

I expect that each page / tab in firefox is placed in its own thread.

However, I experience that when one page gets stuck .. javascript is caught in a wait loop .. that this affects other pages.

Is there something in FireFox that I can change to insure that each page is in it's own thread, and doesn't affect another page's performance?

I lost all my tabs recently & wanted to restore them. The advice via Help topic was to click the 3 horizontal lines, click history & then click "restore previous session" However I do not have that selection. I have the other shown but not restore previous session. I do have the latest version of FF & am on chrome. I was able to restore my tabs one at a time, but in the future I would like the ability to easily restore the whole session. Thanks for any suggestions.

Currently using FF v94.0.1 64-bit (I usually lag an update or two behind to ensure stability -- my highest priority -- and avoid surprises.)


1) I notice that unless there are a sufficient number of tabs opened across a browser window as stretched to a given width, thus triggering the left-right ("<" , ">") tab-scroll arrows to appear, the TAB MENU itself (aka "List all tabs" button, a "v" down-arrow on the far right) is not present. Nor is there an equivalent way to initiate a tab search within the main MENU BAR (FILE, EDIT, VIEW, etc.) that I could find. This restricts access to the SEARCH TABS feature.

This "automatically keep-it-tidy feature" is not really an issue when only a single browser window is open. However, I have many windows (on different topics of interest), each with many tabs.

I can switch to another browser window that has enough open tabs to have triggered the TAB MENU, then search from there. Or I can use the address bar "%" method).

(Actually, I'm pleasantly surprised that Firefox, running on my older PC, is stable with hundreds of tabs open as accumulated over many months. Clearly I should change my habits!)


2) On your support page titled "Search open tabs in Firefox" at https://support.mozilla.org/en-US/kb/search-open-tabs-firefox , it describes (via examples) using the "List all tabs"/TAB MENU button to access the "Search Tabs" feature. It also outlines using the address bar "%" method.

Unless I misread the article, what it does not make clear, is that the "Search Tabs" feature works the same as "% xyz" in the address bar; whereas using "%xyz" (note the missing space) yields different results (apparently the same as "xyz %"; but "xyz%" yields nothing). Nor does it explain the reason for the different results or the importance/desirability/weirdness of using one method over the other -- it simply presents the examples. I believe this help page could use some expansion/clarification.


3) I noticed that when performing "search tabs" via either the address bar (using "%") or via the TAB MENU, the results do not include any open tabs using "containers" (apparently the same as any open tabs within "private" windows).

I am increasingly using the "container" features by opening then permanently assigning many "sensitive" web sites to one of the container categories. The increased security is a nice idea.

However, with many browser windows open, each with many tabs, this inability to search for and conveniently find open tabs is increasingly frustrating and is nudging me back towards NOT using containers.

Can't some solution be found to maintain the privacy between tabs (and perhaps even private windows) while permitting a tab search to work more thoroughly?


In summary, I simply want to be able to find ALL occurrences of any partial string of searched-for text within ALL tabs in either their title OR address, normal AND container tabs, and preferably in normal AND private windows.

At present I see only a list of 12 results and no means of listing more. Sometimes my "known" open (normal/non-container) tab is not present in that short list (perhaps a preference/sort order is needed for tab titles vs. addresses).

Why not a "List more results", or a selector button to scroll-list "10, 20, 40, 100, ALL", or a button to open and continue with a listing of ALL matching results in a separate pop-up window, etc?


Thanks for all your good and hard work!

I work with salesforce and got a MacBook Pro a few days ago and now I worked in some chart and wanted to switch between Columns with the tab button but It won’t work. I always have to click the next column with the mouse. This is taking a lot of time and with a windows pc, I works totally normal. But know I’m really confused what to do. Because when I press the tab button I only goes to the forward and back button and so on

I need so use Firefox as salesforce only works perfectly fine with Firefox. In safari i can switch like with a windows computer

Can someone please help me?

Thank you in advance!!

It's so frustrating that the keyboard shortcut for closing tabs is right beside the one to quit Firefox. I've lost countless hours because of this, and it's so easy to accidentally do. Is there a way to keep this from happening? A simple "Are you sure" confirmation dialog would be great, or I really like the Chrome "hold command-Q" to exit feature. This seemingly simple function is proving extremely difficult to accomplish.

Yes, I'm aware of session restore, but (1) It does not preserve my window arrangement. I use multiple desktops for various tasks, and they each have related browser windows. (2) I need to see webpages exactly as they were when I opened them. Sessions expire, dynamic pages are refreshed, content is removed etc. That is all lost.

I do not want to disable session restore completely. It can still be useful. But, I do not want to trigger session restore automatically every time. Manual activation is ideal.

regarding: "browser.tabs.warnOnClose" I do not want a warning for closing multiple tabs. I often have many windows open and that warning gets annoying. It also doesn't prevent me from accidentally quitting when I only have one tab open.

I tried setting browser.warnOnQuit to true, but it's ignored.

I simply want a confirmation when I use the keyboard shortcut to QUIT. That's it. No side effects. Can Firefox do this?

I searched this forum but couldn't find an answer. I have "restore last session" turned on, but I'd like Firefox wouldn't reopen my last visited site after I close the browser by closing the last tab. In other words: if I close the browser by a regular means (by clicking the rightmost upper X, or by right-clicking the taskbar and choosing close window) it goes to the last viewed site when I reopen the browser – and that's ok – but when I close the last tab and the browser closes, I don't want to see this site again when I reopen Firefox. Is there a way to achieve this? By the way, this is the standard behavior in Google Chrome.

Ever since IE changed to tabs on top firefox coders followed like mindless automatons without any regard to/for Mozilla community and users. We are sick and tired of being ignored. We want/need tabs bellow address bar. Now, tell us how to simply get tabs below address bar or tell the coders to provide us with the option. And, we don’t care about any excuses as previously provided or outright ignored by them.

Before shutting down Firefox I deleted history/cache/passwords etc from the past day

I do this all the time but since I had restore previous tabs selected they always get restored when I start up again

However this time they weren't restored when I restarted

Without closing Firefox I navigated to the sessionstore-backups folder to see what was there but the files were only 2KB - much too small for the number of tabs.

So I installed ShadowExplorer & Shadowcopyview to see if I could recover older versions I was able to locate jsonlz4 files from a few days ago that were around 11000KB in size so I assumed they would have most of my tabs

However when trying to use the files nothing happens - I tried 2 different steps that I read here had worked for others

1 - Renaming previous.jsonlz4 to sessionstore.jsonlz4 , moving to the profile folder (deleting the old one first) and restarting FF

2 - Deleting sessionstore.jsonlz4 and copying the recovered previous.jsonlz4 / recovery.baklz4 /recovery.jsonlz4 / upgrade.jsonlz4-20201014125134 files to the sessionstore-backups folder and restarting FF

I also repeated the steps after creating a separate profile

None of these worked so I tried examining the jsonlz4 files using https://www.jeffersonscher.com/res/scrounger.html but I got an error message 'Session history file contents could not be read?'

Now I've previously used recovered Jsonlz4 files to restore tabs with no issues but this time they won't work

I read here https://support.mozilla.org/bm/questions/1189759 that updates may cause compatibility issues and the upgrade.jsonlz4-20201014125134 file indicates they was a recent update

The recovered file sizes indicate they contain data so I want to know how I can recover it - if not through FF then through some other software

firefox tab name edit: can a user name tab at will ?

right now it has LOGO and "Home" but i want it to read something like OSC-US Office of Special Counsel-Independent Agency-Home because i just do.

i have three other bookmarks for OSC: i can edit the bookmark name from "properties" but have never known whether i can also edit the name shown on a tab.

LOGO Home isn't too helpful to me. but even just knowing that i CAN'T edit tab names will be helpful to know, so i can stop thinking about it and get some sleep after another bag of chocolate-chip cookies. being an american right now is plenty stressful.

who named them "cookies" anyhow?-is it bc they kind of leave crumbs? did i win?

thank you for helping. i do appreciate it.

I got an error on one of my open or pinned tabs (do not recall which it was). I do not recall what the error was and did not screenshot it because I was sure that closing Firefox and restarting it would fix the issue. I did just that, closed Firefox and reopened it to find that ALL of my pinned and open tabs were GONE. This also happens if another instance of Firefox is opened and I close my main one first by accident and then close the other Firefox instance - ALL TABS LOST.

This is what I have done: • I started to restore the pinned tabs as I could remember what they were but I was not able to remember the open tabs that were not pinned • I searched for lost tabs on the web and on the Mozilla support site but was not able to find any useful help - most of it seems outdated or no long compatible with my version of Firefox. • I looked for the sessionrestore files on my local PC but could not find them - this must have changed in some version of Firefox between version 42 and version 82 that I have. • I looked in the AddOn store to find something that would help restore and prevent this issue - but found nothing. A very old post, from 2012, indicated one that did this but it is no longer available. • All of the Options in Firefox to restore previous session, reopen previous tabs and all that were blank.

This is VERY frustrating in that it results in lots of down time to recreate what was open and is equivalent to working on a document for days or weeks only to find out that the Microsoft file got corrupt or did not save properly.

I am using Firefox version 82.0.2 (64-bit).

Two questions: 1/ Is there any way I can get the pinned and open tabs back from the previous session? 2/ What can I do to avoid this issue EVER happening again.

Thanks!!!!
