Firefox Community Forum

Long story here:

A few weeks ago, I lost internet connectivity on my desktop PC at work running Windows 11. I checked Firefox, Edge & Chrome but couldn't access any site. It took a few hours and a lot of updating Windows, rebooting each time the internet kicked out, but I got it to work again.

Fast forward to this past Monday the 29th when the issue happened again. Within roughly a minute, the internet just died on my desktop again. I grabbed my work laptop, also running Windows 11: same issue happened within 60 seconds. I checked Firefox on a desktop running Windows 10 - had no issues at all.

Today, I installed Firefox on another laptop (the same model at the other one) running Windows 11. As soon as it synced my account, the internet stopped working. I though it may be the Sync option, so I reinstalled Firefox on my laptop but did not log in to Sync - the same issue: dead internet within 30 seconds now.

I have:

• Run anti-virus
• Run network diagnostics and reset
• Rebooted a multitude of times
• Uninstalled, reinstalled at least twice
• Run troubleshooting in Firefox (which I cannot attach the logs due to it being uninstalled right now)
• Checked to make sure my modem/routers are working right (no one else in the building has this issue and we all use Firefox, but none are synced to my account)
• I even asked my company's tech team (who are mostly software developers) and they said No, sorry, we don't help with that (wonderful right?)

I've attached a screenshot of the OG machine's information. Not sure if it will help at all, but it's worth a shot.

Good morning, Woke up, noticed my screen on (was in sleep mode), guessed PC had restarted itself overnight, that happens, opened Firefox, click sandwich Click History "Recently closed tabs" and "Recently closed windows" are not options I can click...

what the heck please help! I'm going back to bed....

99% of the time, site's work just fine with strict cross-domain referral policies. Sometimes they don't. I don't want to change my browser-wide setting everytime I use ONE site. Is there anyway to add a site-specific exception for referrers?

Sehr geehrte Damen und Herren, ich habe neulich bei GMX einen neuen E-Mail-Account eingerichtet, der auch innerhalb GMX problemlos funktioniert. Bei der Integration in das Programm Thunderbird gibt es jedoch Schwierigkeiten, obwohl ich sämtliche Serverparameter korrekt angegeben habe. Ich konnte den E-Mail-Account nicht einrichten (s. Bild im Anhang). Was habe ich falsch gemacht? Mit freundlichen Grüßen Klaus Reißig

Hi,

When i switch between two tabs by clicking with my external mouse ( I am on one tab and then point and click on another) and then directly start to scroll the page zoom like it does when i hold ctrl+zoom. What causes this?

It does not do the same in other browsers or other apps. It does the same with external mouse and track pad.

Win 11 Pro Firefox 143.0.3 (64-bit)

I'm using version 143.0.1 (aarch64) on macos 15.6.1 (24G90). Ever since I updated to 143, many web sites no longer work.

For example, I get a completely blank page at https://banking.dkb.de/ - see source below.

At https://outlook.office.com/mail/inbox I get an error page - see below.

Here is another example of a blank page: https://www.aircanada.com/home/de/de/aco/flights.

Moreover, the inspector is completely blank for _all_ pages.

The abve pages work fine in Safari. I have used FF for ever since the first release, but am considering ditching it now. I can't find anything about this problem googling.

Please help!!!

Hello- When I am on a website and click link I would expect and want a new Tab to open-- I want it to open it in a new Tab and leave the page I'm on alone so I can go back to the original page.

Instead, Firefox overwrites that page and the tab with the a new one, and I have to hit the back button to get back to that original page. And most often the back arrow button is grayed out and I can't get back at all.

In settings, I've tried checking the box for: 'Open links in tabs instead of new windows' but that doesn't do it. I've also tried checking the box, 'When you open a link in a new tab, switch to it immediately,' and that doesn't do it either.

I know that a work-around is to hold down the Ctrl key while clicking a link, but I'd like to set it as a default so I don't have to do that. That's a pain and not a natural function when browsing. To be sure, I want to click on links and that creates a new Tab without Ctrl Keys.

Thanks!

При заходе на сайте ya.ru и если на нём имеется строка с видео или поиск с алисой, то начинаются сильные фризы. Это ошибка именно в firefox 142, проверенно.

When I turned on my computer this morning, and opened Firefox, it froze, and had to be process-ended by Windows.

Subsequently, it also caused Windows Explorer crash.

I was forced to hard-reboot my computer, and restarted it to find all my tabs gone and unrecoverable, and all cookies deleted.

However, my browsing history remains.

Furthermore, my attempt at recovery of this data via the automated backup taken Monday 29 September 2025 - three days before this post - accomplished nothing.

I have looked in several places here, and found no help at all in recovering lost tabs. All threads remain unresolved.

Please provide troubleshooting assistance ASAP.

(And please be aware that the software had to be opened in order to post this question.)

When using "about:support" on Firefox I'm not seeing my "profile path". Are there instructions on this method to make sure I don't loose all of my OneTab-tabs, or should I use another method? A FF comment: If you have a backup of this profile folder than you can restore your data...where do I find this folder?

You also suggest using a backup program--not sure what this means. How do I run backup software on my computer to restore my Firefox profile folder (a file path) ? I do have an external hard drive continuously backing up my files, however I don't know if this will back up browser settings/data whether it does or not- do I need to search for doing this from the manufacturer or from you.

Another suggestion from your help articles: If you don't use our "backup/sync feature, then the only way to recover the deleted data is if (a repeat of the above suggestion )you run backup software on your computer that can restore your Firefox profile folder.

I'm confused on what the backup/sync feature is referring to, unless you're talking (install FF on my Chromebook" so that it puts all my settings and data onto that device? ...sorry.

My problem is Microsoft is giving ppl until Oct 13th (2 weeks away) to upgrade to windows 11. I'm afraid I'll lose all of the FF windows and tabs that I moved into OneTab. This was hundreds of hours of work not to mention the amount of money I've paid to access these websites for research.

Any response would be greatly appreciated...I saw a comment that FF is working on a solution for this but I may not get it until it's to late.

OMG..I just saw and update available for FF. Based on what I just read, it's possible I'll lose all of the data in OneTab, What should I do...thinking! First thing is I'll look to see what the update is about, then decide.

I just updated to 143.0.3, and unless I open FF to its full width now, my clear-browsing-data and zoom icons have been disappeared from my menu bar.

The reason is because large (one-inch!) empty spaces have suddenly been inserted at the far left end of the menu bar (next to the back arrow) and between the hamburger icon and minimize "-" sign. It's not possible to remove those blanks via customize.

I click on my "clear" and "zoom" icons hundreds of times a day and I prefer having my browser non-full-width (prefer 2/3 width).

Anyone know what caused this and/or how to fix it (apart from rolling back to 142). Once again Mozilla has broken something that worked perfectly for me for many years and I suspect it has something to do with more screwing around with tabs. (I do use a CSS file solely to keep tabs on bottom.)

Alternatively, is there a way to shorten the address bar? That might create room for my add-on icons to re-appear while leaving the spurious blank spaces on the menu bar.

Thanks in advance! --KK

Using FF 143.0 on Win10 64 bit. I do not use any password manager. Before I logon to any site, as a matter of course, I clear all cookies and history. I logon just fine to many sites.

However, only at: amazon.com do I see this pop-up. There appears to be no way to actually verify it is really me. And there is no difference in action between "Cancel" or "X' closure.

Lastly, this pop is modal. It can not be bypassed. I have to kill it to continue to amazon.

amazon is the only place this appears, and I really don't know what is generating it.

Any clues anyone.

See attached. When I move the browser's right-edge toward the left-edge, the whute square's right-edge moves to its left-edge, the same amount until its gone completely.

Thanks for your help.

Link sent via https://www.mozilla.org/en-US/newsletter/recovery/ does not allow unsubscribing from Ten Tabs <firefox@mail.mozilla.org> newsletter that is sent frequently without opt-in or out options.

My password/bookmark/history disappeared with Windows recent upgrade. How do I get everything in that area?

Also, I opened the Share option and it populated with something I did not want shared. I attempted to delete the entry but it is too long. How do I remove that entry? Could you help by walking me through these issues?

If this is a duplicate of the issues I appologize.

Your help would be greatly appreciated,
