Dear Mozilla Support,

After some update (I think from 89.0.0 version of Mozilla Firefox - this version with new looks of tabs) I notice flickering on the tab when I loading website or refresh website. This looks very strange. Like I said I dindn't notice any issue with flickering on previous Mozilla Firefox versions. Only with these new versions with new look of the tabs. I didn't remember if it was 89.0.0 version or 90.0.0 version. I don't know if it is problem with the machine but I didn't notice this issue on another computer with 90.0.2 Firefox version but with Windows 10 OS. I also noticed this issue with Firefox 90.0.0.2 with Windows 7 OS on another computer so I don't know if this is problem with two computers or Firefox itself. Can you help me?

Yours faithfully, Piotr

I generally have loads of tabs open, and until recently this wasn’t an issue (perhaps until last upgrade?), but now, I can hardly move between tabs, the drop down list showing tab selection doesn’t work, nor does the left/right arrows. When I delete a tab, it leaves a ‘space’ where the tab was, only ‘back filling’ after I’ve opened up another tab to full screen mode and then minimised it again, at which point it goes to the very left-most tab and the only way I can get to tabs further down the list, is by deleting them in the manner described. I’ve actually got 2 laptops (Win 7 & 8.1), and it’s now happening on both of them. This might have something to do with memory management/the computer’s page file, but as things stand, I’m SERIOUSLY going to be switching to another browser - despite sticking with Firefox for many-a-year. BTW, I’m actually writing this on my phone, as I couldn’t now do it on either of my laptops (hence I’m currently unable to attach anything/provide screen grabs etc. I guess the only way to ‘clear’ this issue, would be to either close/restart Firefox or my laptop - neither of which I really want to do. Is there a way that I can use an earlier version of the browser and prevent it automatically updating? Yours, a now very frustrated longtime user,

My current browser (version in header), has stopped saving previous session. I followed the advise from FredMcD on this page https://support.mozilla.org/en-US/questions/1345654, and the browser is still not saving tabs. From Fred's post, I couldn't find any "sessionstore.jsoniz4" files in the browser folder. I did find the "sessionstore-backup" folder and deleted it. I restarted Firefox, opened a folder and then stopped Firefox and restarted it again, and I only went to the Firefox Home page. The "restore session" box is selected.

What else should I try??

So I have been having this issue lately where my computer just won't respond, and the only thing I have to fix it with my limited skills is to force the computer to power off and restart it. Unfortunately, this tends to result in me losing my tabs and having to find them all over again in Firefox. Usually it's not a big deal, as it's just a few tabs missing, and I can just remember what I need. This time, however, I've lost a weeks worth of tabs, and it was a very busy week. I can't remember what tabs I had open, and the few things I've tried to get them back, are not working.

I have, unfortunately, already tried restarting my computer, which inevitably led to firefox being closed and reopened, and though I have tried to find my previous session data in the profiles information on my computer, it only has this session that is currently missing a week of work, and the session from the week previous. I am very distressed right now, not gonna lie.

Recently i found that the memory usage can be very large when watching live-stream,tried many ways to fix but none of them was useful. Then i found the new function of "minimize memory usage" button,it is useful,but not so convenient.Can you please add a new way to use this function? Like: set a number of memory usage(for example 256000KB),when reach this number trigger the "minimize memory usage".Then it will be like "auto minimize memory usage". Or,you can just set an UI button on the toolbar to trigger "minimize memory usage".

Please check my screenshot Pic1:It's the live-stream tab,memory usage 1800+MB Pic2:But it seems not so large in "about:performance"

Good morning, There are multiple questions. 1. Now everytime I click on a link in an article it opens a completely different page of firefox instead of just making a tab on the line with all the other tabs. It also loads that new page half way off the screen on the right hand side and I have to drag it over, open it full sized and then screw around with cutting and pasting the url into a new tab on the old firefox page. How do I stop it from doing this? It's realllllly annoying.

2. It is screwing up some of my graphics by putting horizontal lines into the picutres to where you can't view it. Specifically on jigsaws from jigsawplanet.com. I work on a gaming site and this really impacts my ability to do my job (or have fun).

3. One one particular site HEXrpg.com, I set my view at 120% and every page I go it it reverts it back to 100%. This did NOT used to happen and it only seems to be happening on that particular site..... However, it could be on other sites as I've had to set my entire computer to 120% now so I can read the posts on that one site and now everything is too big for my screens in the other sites.

I don't know what you guys were trying to do, but whatever it was, can you please put it back to the way it was before this last (possibly last 2) updates. If not I'm going to have to switch to Edge or Chrome and I really don't want to have to do this because I've been with Firefox forever. HELP!?! Deborah DeVane

All my important tabs = gone. Nothing under recently closed windows. Most of them too old to be found in recent history. I'm mortified. I normally love Firefox updates but now I want to yell at someone :(

A couple days ago, late, I accidentally closed my main Firefox window before a little window that I'd forgotten was there - and all my 76 tabs disappeared. 1st thing yesterday I tried - 3bar / history / recently closed tabs - but the only thing in there was the one tab from the small window. Urg! I tried that and - 3bar / history / manage - where I could see my tabs but could only restore 1 at a time - not good for 76 tabs. I read a bunch of different questions about this same issue, and tried the suggestions, including some app called scrounge, but none of these restored my tabs. Help!!!!

Hi, I'm using the latest Firefox on a Windows 10 Dell laptop. Typically I have a lot of tabs open - 500+ sometimes. When I think this number of open tabs is getting absurdly large I do some housekeeping and close tabs individually that I do not currently need. Those I might want later I bookmark and then close. When I shutdown my computer I close Firefox first When I close Firefox I get the message "closing 5xx tabs". If there is an option I confirm. When I start my computer again, and then start Firefox, all of the previously open tabs are restored, which is awesome. Less awesome is that all the "housekeeping" individually closed tabs (which were not open when I shut down Firefox) are also restored. How do I prevent these individually closed tabs reopening while still having the tabs which were open at shutdown restored?

Thanks so much.

Since one of the last updates the behaviour for the tab re-sizing got messed up.

When there are only a few tabs with full size, those as well as the additional plus icon is shown. But when there are more tabs and they are re-sized, then the right side gets cut off. First the new tab icon dissapears and then also the last tab get's cut off.

I attached a screenshot with three firefox browser windows showing the problem, as well as a forth one with only 3 tabs open, which are shown in full size including the new tab icon.

This is a new problem as the tab resizinng and the new tab icon used to work perfectly fine no matter how many tabs were opened.

By mistake, I close a window with lots of opened tabs and can not get them back. In the past when this happened I went to history but now there's no available option in "recently closed windows".

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.

When video/audio starts playing on a browser, the tab title displays 'playing' text. This additional line resizes the window height and causes the tab content to resize too. For example youtube starts resizing video window height and width - and this is very annoying. How do I remove 'playing' text from tab FOREVER?

so i went to a website called imaker.com and when when i switch tabs to another page (like this one) the tab for imaker.com keeps flashing "1 new message" and then the website name and their icon.

how the hell do i stop this from happening as it's extremely distracting.

Hello. Im new to the Mozilla Support community

And heres the issue: Firefox keeps opening tabs randomly which are related to pornographic websites like xxnx, pornhub, evilangel n' etc..

Heres things ive tried, but didnt work: -Install tdsskiller & scan -Scan with Avast Antivirus -Uninstalling Firefox and delete registry entries -Getting IE8 or G**gle Chr*me for Windows XP SP3

Any way to resolve this problem? i can't watch these things!

Hello, Firefox support team!

Could you help me, how can I ultimately, once for all the time, for all the modes restrict to open new windows? The problem is the Firefox browser open new windows if the browser was closed and Im open a link from a different application (cant solve that at all). Or it was opened but somehow for some sites it opens a window instead of tabs. To be honest it can be a big and annoying issue on mac, if me app in full screen mode. And in genereal also. It is something I dont expect from app. I tried all the variants I found or learned in about:config which a connected with windows. It not helped me at all.

So my browser pages weren't loading so I went to my windows 10 settings app and went to "Apps" and then I clicked on FireFox to uninstall it but it gave me an option to "Refresh" it and so I did that and it fixed the issue I was having but ALL my tabs are gone and I NEED them back. Please tell me there's a way to get them back. I think I even had important ones to. ;-; ;'(

The images or symbols for different websites are not loading in tabs. I have reset several times. I have closed out of the widows and nothing. Is there a fix to have tab images populate normally? I attached a snip of 4 different websites all had images in 2021 and now they will not load.
