Using Firefox on windows 10 pro, 64 bit

Since updating to Firefox 125.0.3 (64 bit) , I am getting all sorts of website problems with font sizes. Some are all extremely small like on google news, others have widely mixed sizes, extremely large and extremely small. Even on this page, support.mozilla.org, I have to zoom 250% to make it readable.

I tried troubleshoot mode and there is no difference. The problems are still there.

I tried the Edge browser and the problem is not there.

I didn't have this problem before the update. I tried adjusting windows and the screen dpi, but I can't find a solution. Just seems to make things worse.

Anyone else having this problem? Any suggestions for a solution ?

I experienced problems with Firefox on different Windows 10 clients. The problems are only with Firefox, other browser like Chrome or Edge have no issues. The occasional issues are that Firefox loads the websites either very slow (~ 30 to 60 seconds) or sometimes not at all. At the same time, other browsers like Chrome or Edge load the same websites fast and reliably.

All affected clients have a fully patched Windows 10 with the latest build, up-to-date Firefox versions, recent processors and plenty of RAM and I periodically clean cookies/website-data/cache/history.

What could be the problem and the solution?

Firefox can't seem to hold on to, say, a banking website or web page when I navigate away to another app, such as to answer the phone!

I'll be on a banking website, and when I get back to Firefox from the call 1 minute later, it will greet me with the login credentials page.

If I'm trying to login, and I'm on the 2fa page, and I answer the phone call to get the code, when I get back to Firefox, I'm no longer on the 2fa page, I'm back on the login credentials page.

If I'm trying to log in, and I'm on the 2fa page, and I navigate to the email app to get the code, when I get back to firefox, I'm no longer on the 2fa page, I'm back on the login credentials page.

The situation forces me to use text messaging for 2fa when using Firefox.

I tried recreating the situation in the Chrome browser, and it doesn't seem to suffer from this problem. I navigate away to the email app, come back to Chrome, and I'm still on the 2fa page.

The situation exists for most banking sites, but is not exclusive to only banking sites, as it occurs on many other types of websites, as well, requiring 2fa logins.

Is there some setting in Firefox that I'm overlooking that causes these websites to default back to their login credentials pages just because I went to another app on the phone for a second?

I always keep two Youtube tabs open at all times on my computer. After a while of running, however, the site starts to get increasingly laggy, in a way that simply reloading the tab does not fix. (I am aware that this is likely a result of one of the extensions I have installed that affects Youtube's behavior, specifically SponsorBlock and Return Youtube Dislike, but I am not willing to uninstall these.) I also know of a "force reload" - pressing ctrl + shift + R instead of just ctrl + R in order to clear the cache or something.

However, whenever Youtube starts getting really slow, I instead like to do something I call "crashing the tab" - I open my system monitor, look for the current most CPU-intensive "Isolated Web Co" process, and end it. This pops up an error message in Firefox that says "Gah - your tab just crashed!" and offering me the option to restore it. After restoring it from this window, the performance is back to normal.

My question is, is this beneficial, or is it functionally identical to a normal force-reload? Is the improvement I see between this method and force-reloading the page just placebo? And if not, is there a simpler way to do it without opening a second program?

I have made Firefox my default browser, and set Google as my default search engine.

I'd like to keep it that way, BUT ...

Every morning when I come to work and open my browser and begin to search .. Yahoo comes up .. or Bing ???? I delete them, and again set Google as the default ... BUT FIREFOX CONTINUES TO REVERT TO YAHOO, or BING SEARCH RESULTS  ?!?!?!?!?!?

Even when I deliberately open Google and search in Google .. the results appear and then suddenly, a new window pops up with Yahoo results, covering up the Google results????

How can I make Firefox respond to the default search setting I choose????

This is intolerable. If I can't get ride of Yahoo and Bing and all these other inferior search engines, then I'm going to go back to using Chrome.

I need to go over the head of the Mozilla Triage manager who has left https://bugzilla.mozilla.org/show_bug.cgi?id=1406865 open without a resolution for **seven years**. How do I do that? This is a bug reported in Firefox 57 and **still** not fixed in Firefox 125. I cannot find any support category anywhere in the Mozilla website that covers appealing a decision by one of their employees. The last comment from this uncooperative indivisual is "But given we support it on macOS and Windows yeah, it seems not very objectionable." Who is this **clerk** to override the fact that a number of customers very much find this "objectionable". I cannot find anything on https://www.mozilla.org/en-US/contact/ that addresses this issue. I cannot find even a surface mail address for Mozilla. For example my complaint has nothing to do with any of the following:

   I’m having problems with using Firefox
   I want to donate to Mozilla
   I have questions about using Mozilla’s trademarks
   I’d like to report misuse of a Mozilla trademark
   I want to hold an event in a Mozilla space
   I want Mozilla to sponsor my event
   I’d like permission to use a Mozilla logo
   I’m interested in Pocket’s sponsored content on Firefox
   I’m a member of the Press and have a question for Mozilla

Yes I am having a problem with Firefox, but the clerk responsible has, through sitting on this issue for **seven years**, basically told the entire community that he doesn't give a reservoir.

In particular I feel this unacceptable behaviour should be brought to the attention of senior management, but there are no contacts for anybody in senior management.

My Firefox settings are configured to "Open previous windows and tabs" on Startup. This worked fine until this morning, when I lost all of the tabs in my session, including the pinned ones. The last time I closed Firefox, there was only one window open.

I have already tried these ideas to restore the tabs:

• CTRL+SHIFT+T: Does nothing
• CTRL+SHIFT+N: Does nothing
• Three bar menu -> History -> Recently closed tabs: The list is empty
• Three bar menu -> History -> Recently closed windows: The option is greyed out
• Three bar menu -> History -> Restore previous session: The option does not exist in the menu
• Open user profile folder and open sessionstore-backups folder: There are three files named "previous.jsonlz4", "recovery.baklz4" and "recovery.baklz4". They are each 2KB and contain only an empty tab with the URL "about:home". There are three additional files starting with "upgrade" but they are from too long ago, so they don't contain the tabs I require.

The contents of these tabs are vitally important for my work, so this is causing me significant stress. If anyone can suggest ways to recover my previous tab beyond the documented fixes, I would greatly appreciate it. Thank you so much to anyone who can help!

Hi Firefox Support Community,

I've been exploring the reviews on SGEats and noticed some performance issues while browsing the site using Firefox. The site has numerous high-quality images and interactive elements which seem to cause slower load times and occasional lag.

Are there any specific Firefox settings or extensions that could help improve the performance for such media-heavy websites? Would enabling or adjusting hardware acceleration settings make a significant difference in this case? Are there known issues with Firefox handling similar content-rich websites, and if so, are there any recommended troubleshooting steps? I appreciate any insights or recommendations to enhance my browsing experience on SG Eats and similar sites.

Thanks!

The webcam video image is being reversed or being flipped horizontally when using the latest version of Firefox. This is not happening in other browsers. I reset Firefox, but the issue still occurs. Can you advise/fix please?

when I log into wetransfer.com the file transfer box is greyed out and I cant use. It works in Microsoft edge.

Hello, I administer a small fleet of Ubuntu desktops. For a variety of reasons we avoid using Canonical's Snap package version of Firefox.

Currently the fleet is using Firefox installed from the Mozilla Team PPA repo. However that repo can be incredibly slow and after reading about the new Firefox deb packages [1] from the Mozilla APT repository we would like to move to them. The problem is that these packages lack Apparmor profiles, so unfortunately my security team won't let me use them.

Would it be possible to add Apparmor profiles to these packages please? They would need to be applied only when an OS has Apparmor enabled, which may not be the default for Debian.

Thank you!

Hi All,

I would like to change the color of the two highlighted URLs in the address bar's drop down list to what they were in FF 88 - the one that is currently selected with the cursor keys, and the one the mouse pointer is over.

The first screenshot below is of the highlight colors in FF 115/125. You can see two different shades of gray, the darker gray being the URL selected with the cursor keys, the lighter gray being the one the mouse pointer is over.

The second image shows the colors from FF 88, the URL selected with cursor keys in blue, and a dark gray for the one the mouse pointer is over.

Any help in modifying these colors, and the radius of the selection is greatly appreciated!

Hi folks,

I've searched, but I haven't found anything to help with this particular situation ...

I love Firefox/Mozilla Sync and I use it a lot, but I've recently had a desire/need to set up a scenario that some may think perculiar - let me set the scene ...

• Work PC running Firefox - 1 profile
• Work VDI running Firefox - 1 profile
• Work laptop running Firefox - 2 profiles (work & personal)

Mainly for the sake of sending tabs to the appropriate Firefox profile on the laptop, I want/need to be able to config things in Sync to treat those 2 profiles as being different entities. Currently, it appears that all profiles on a device (or within the same user profile on a Windows computer) are treated as the same entity by Sync.

Any ideas on how to achieve what if trying to do? Is it possible with Firefox/Mozilla Sync?

Thanks for your time.

BTW., for clarity, if it matters, the devices listed above are all Windows. FWIW., I also use FF on Android and Linux ... and MacOS.

When I try to customize the toolbar in Firefox 115.10, the browser tries to change the page to the customize toolbar / overflow toolbar page. However the page flashes on and then reverts to the normal browser page. The page showing customize toolbar/ overflow toolbar, is transient and does not last. So I can't even customize the order of the buttons on my toolbar. This wasn't a problem a few days ago before the switch to this latest version. In particular I am trying to change the position of the "home" button to the left side of the address box. I just can't bring up the customize toolbar page. I'm not talking about the position of the add-on or extension buttons...just the home button. Hope this is clear. By the way, I've even tried this in safe mode to no avail.

I am replacing a ten yr. old Dell Desktop with a new HP Laptop. Can you please let me know how to get the new laptop working with my existing Firefox (v125.0.3) with current add-ons, extensions and settings? Thank you for your time !! Rick Perry

I can hear NO AUDIO on ANY webpage, when in Firefox. I have gone through all the suggestions on this page: [https://support.mozilla.org/en-US/kb/what-to-do-if-firefox-wont-play-any-...] but still have the problem.
