It seems like almost every time I do a Windows Update on and sometimes when I just restart my Lenovo IdeaPad 3 my language gets changed from American English to French. Even some of the add-ons change preferences. Since I don't speak or read French it can be a real hassle to get everything changed back. What I usually end up doing is going to the page on the Mozilla site that has different downloads for different languages and I download the correct one. Once I install it over the existing installation things go back as they should be until I do another Windows Update or like I said before, sometimes after just a restart. This just happened again a few hours ago when I did a Windows Update. All the menu items and drop downs were suddenly in French. My Forecast Fox changed to Celsius instead of Fahrenheit. My Notifier for GMail changed to French. A couple log in pages for some web pages were in French. This never happened with other laptops I have had that were different brands. I once tried just uninstalling Firefox and then reinstalling the correct language version and things were fine until the next time I did an update. My preferences are set to how I want them and I just don't understand why it keeps getting changed.

Hello everyone,

this here is a really odd problem and not one of the usual "firefox slow, internet bad" → "read the faq" problems as far as I can tell.

The problem: When using Firefox (110.0 64-bit Windows 10) I noticed already a while ago that downloads are slow, apparently frozen from time to time, websites took longer to load and looking at speed tests, I got really bad results. Furthermore, Firefox seems to slow down my internet speeds of the whole system, as I can observe in other applications which want to download or upload data. As long as Firefox is running (even if I am just in the default tab and doing nothing in Firefox) it slows the internet speed of the whole system down.

So I tried a plethora of things to fix this and I can rule out the following possible causes with high confidence:

• History, Cache, Add-Ons and so on: performed a clean re-install of Firefox, cleared all cache and history data, removed add-ons, reset to default, etc..
• ISP problem: performed repeated speedtests from other devices within the network, everything is fine within my local and wide area network, ISP does not report any problems
• Firewall & AV: turning on / off, even uninstalling, no effect observed
• Driver problem: driver updated, driver removed, used default Windows Driver, used Troubleshooter etc., nothing helped.
• OS issue: Nope. I even performed a clean new installation of Windows today, the problem remains. Furthermore: I ran the speedtests using Microsoft Edge and there are no issues (as long as Firefox is not running.)
• HW / System issue: Nopes again. I have used a live Ubuntu-image to cross-check whether the HW might be an issue, but running speedtests using Ubuntu and Firefox worked well.

I did not observe similar effects on other machines using Firefox under Windows in my network. So it seems to be a very specific problem within Firefox under Windows 10 on my machine.

By the way the machine: HP Pavilion Gaming - 15-dk0200ng CPU: Intel Core i5-9300H RAM: 16 GB DDR4-2666 SDRAM WiFi: Realtek RTL8822BE 802.11ac (via PCIe) (I also have an Ethernet chipset on this system, but since I have tested everything using only WiFi I'll omit the info here.)

So is this a bug of Firefox? Or am I missing something?

Attached are some screenshots of the disappointing test results using Firefox. (I have similar problems on other sites like speedtest.net or the speedtest of Google). As reference: I've got 500 Mbit/s downstream and 50 Mbit/s upstream. Usually these speeds are achieved from other devices (or other browsers on my system), or are at least within the top 80%. But what I get with Firefox is significantly worse. It's also strange that the speed goes up first, which is fine, but then falls down completely after reaching some point. A few seconds after that it goes up again, but much much slower.

Thanks in advance for any help!

Firefox updated yestarday. I see these changes: extension are gone, theme settings were switched from Dark to Light, "Startup -> Open previous windows and tabs" option went from checked to unchecked. These things are still fine: bookmarks, saved passwords and history. Tried reverting to older Firefox version, but it didn't help so I installed the new one again. I then checked profiles in AppData folder and I see three of them. The problematic one I just described, the one that was automatically created when I tried to downgrade to previous Firefox version and the one which only contains empty "parent.lock" file. There is nothing useful in "Extensions" folders (first profile has addblock extension file which I just installed, second profile has langpack extension file). I don't particularly care about which specific extensions I used since I can just reinstall them when I need them again, but one of those extensions contained custom written scripts which were running on specific sites to help me with my work. Those scripts are what I really want to recover.

The option to restore tabs and windows is no longer working for me. I normally have a dozen tabs I work thru every day. Yesterday when I shutdown Firefox, all those tabs were there. Today when I open Firefox it only had to single Firefox default homepage. Checking under History there is no option to restore previous tabs, and the recently closed tabs was empty.

To test, I opened an IMDB page and pinned it. I then went to Wikipedia. This gave me a pinned and unpinned tab. I shutdown Firefox via the "X" to close the window. When I restarted Firefox there was only the default homepage. Neither IMDB nor Wikipedia showed up under recently closed tabs and no option to restore the previous session was available.

I have operated Firefox this way for several years. I don't know why this behavior is no longer being supported.

In Ebay - Print invoices link opens print preview window inside page -> I can view document (invoice) then click print button to open print window -> window opens but the document is blank, just a white page, no text. If I click print, it just prints a blank page. I can download the document as PDF from print preview page and this prints ok but I can't print directly from the ebay page. This only happens in Firefox. Works ok in Edge and Chrome. I have uninstalled Firefox including profiles etc and re-installed, problem still exists. I can print shipping labels via Ebay just not invoices. No issues with printing anything from any other ebay page or other websites.

How do we disable "Thank you for loving Firefox" tab that keeps opening. Have tried several of the tips provided online but does not work. Deleted and re-installed Firefox and it this annoying tab still opens. Please advise how to fully disable or please resolve in next update. Have Firefox on several other computers and this does not open. Thanks!

After a recent reinstall Firefox seems to have a problem. This seems to be only Firefox specific and I can't find a working solution online after googling.

Youtube videos work, although they do give errors sometimes. A refresh always fixes those. However Twitch/Youtube live streams do not, and display a generic error message. When trying other browsers the live streams work fine.

And old Bugzilla post (https://bugzilla.mozilla.org/show_bug.cgi?id=1467495) describes what I believe to be a possible reason for the problem, however following the solutions in that thread have not yet lead to a solution.

Any further insight or solutions would be appreciated.

Can't install Firefox on new WIN 11 laptop. Every attempt leads to the Microsoft store which no longer has Firefox in it or to a dialog that says Firefox is not a Microsoft-certified app. I REALLY don't want to use Edge! Thanks in advance for your help. Steve [email removed from public]

How do we contact customer service with trouble shooting issues? It is unacceptable not to have a number to call or at least a chat function to talk to a live specialist

Win7 x64P , FF110.0 (64-bit) I am trying to change the image for a 'new tab' shortcut so I can recognize it visually , the only option I see is to select a URL for the image. (local image would be handy)

I uploaded image to drive.google & shared, inserted the link & save. But is shows just blank.
It shared it properly & tested when logout.

but its a share link & not really an image link.

I have read https://support.mozilla.org/en-US/kb/customize-items-on-firefox-new-tab-page?redirectslug=customize-shortcuts-your-new-tab-page&redirectlocale=en-US#w_add-a-shortcut

Firefox was working like a charm on my MacBook Pro '16 19 with Venture 13.0 macOS, without any issues. But somehow, after I did upgrade to Venture 13.2.1, Firefox started random hangs/freezes after each 30-60sec. And it takes ~5-10sec. I started to get random panics 2-3 per day.

I did not changed anything in the settings. This also happens in Private Window mode. I usually restart the computer everyday. (Eventually a new Firefox instance each new day, before Ventura 13.0 and still do after upgrade)

I have read the followings:

• https://support.mozilla.org/en-US/kb/diagnose-firefox-issues-using-troubleshoot-mode
• https://support.mozilla.org/en-US/kb/refresh-firefox-reset-add-ons-and-settings

But didn't help me. I have everything (tabs, favs, extensions, works, etc.) so that I do NOT want to reset/refresh ANYthing. I'd prefer to fix the root cause and understand the issue why it keeps occur.

I either change my main Firefox browser (after 8+ years) or look for a solution to fix the root cause without doing any refresh or reset (or something that cause data lost).

Is this a known issue?

Could you please help me on this? Thanks!

My Environment:

• Firefox 110.0
• macOS 13.2.1

Also, in the Troubleshooting Information section below, browser somehow couldn't collect to data and showed a "manual way documentation" button. I clicked it and it redirected me a doc. When I back to previous page, I lost the data I've just written here. So had to rewrite everything... Can you please fix this?

Not sure what happened with my last update installation but I use Ancestry to do my family tree. It will load to the main page but will not let me get my dna matches. Please help.

I am running FF v110.0 on Windows 10 (64). This version automatically downloaded and installed without my permission (I never allow any software to automatically update) - I found out about this a week or so ago. I've also reset the update settings to what they've always been.

Anyway, since that upgrade I am getting a blue box around whatever control I click on. This occurs on most web sites. I've tried the various suggestions from years ago (troubleshoot mode, about:config 'browser.display.focus_ring_on_anything' and 'browser.display.show_focus_rings' = false). This does not occur on any other browser and didn't occur on Firefox until the latest update.

How do I get rid of this? It is very annoying with several web sites I use daily.

Thanks,

Click on the Preferred Location dropdown with Firefox for Windows. You get the following.

Now do the same thing with Edge/Chrome on Windows or Firefox for Mac. You get this.

The font being used is Adobe ProximaNova-Reglar. Why is this happening and what can I do to fix it.

Ever since last Firefox update have been unable to access my DNA matches in my Ancestry program. Are you working on fixing whatever it is that you did to cause this? Heather

I'm really not sure how something like this can happen but I have lost access to your products. My favorites, passwords, DuckDuckgo, background, and everything. I thought that once I signed into Firefox again all these saved items would come back but nothing has. It's like someone pushed a button and changed my world using all the products that you offer. I don't know how to retrieve these needed items and I'm hoping hard you can return my Mozilla world to me. I don't really understand how this could have happened but I'm hoping it wasn't something I did. I can't give you any hints that might explain how something like this could happen. When I tried to sign into firefox Microsoft Edge offered to provide the password but I don't want to go near their products. It seems when you go that way Microsoft will add a dozen things I don't want. I'd like to thank you for any and all help you can provide to me. Also thanks for your time. Most sincerely, Robert Auerbach

Hi Mozilla, I subscribe to the videopass on motogp.com. I recently went on to renew my subscription but couldn't proceed because of the following message. "Sorry, we are unable to proceed with your purchase as we have detected that the billing address does not match your location" My profile location is "The United Kingdom of Great Britain and Northern Ireland", but my billing location is "United Kingdom". They are apparently two different locations according to the website. I must add, these locations are from a dropdown menu so I cannot change them. I emailed motogp and their tech people reckon either my browser (Firefox) or my internet provider (Sky) could be having a conflict with the payment platform. What do you think? Personally, I think It's the website's problem but any advice would be helpful. This is the first time I have tried to renew, usually I just let it auto-renew. Regards,

Steve.
