Firefox Support Forum

Currently the fonts at the top of the page (tab headers, address bar, search bar, booksmarks) are all set to a larger font. I don't know how they got changed but they are too big now. If I try change font size and style in settings nothing happens. It is not how it looked on first install and using another browser has font sizes of a more practical size. I have tried uninstalling/reinstalling Firebox and also doing a refresh and it doesn't change anything.

Its almost like a bug that has made Firefox set these fonts larger than they should and not able to modifying them again.

I cannot for the life of me work out how to fix this and its very off putting to the point, short of a full OS reinstall I'll have to start using another browser.

Same issue as [this poster] . I've seen no correlation between pixelsPerPx and cursor size, but have noticed this behavior doesn't occur in Manjaro's version of FireFox, so I started asking myself, Self, "what might the differences be here?" Answer I got back: they (Ubuntu 22.04) have bowed to the god of SNAPpiness, and Manjaro still hasn't (gets updates from Mozilla rather than the snap store).

Am I on to something here? What else could be the difference between the two flavors of Linux? Any help would be greatly appreciated, my tired eyes have forced me to change default browser to Chrome or Edge, both of which don't seem to respect my privacy like Firefox. Interesting to note that Thunderbird doesn't have the "flea-size cursor" and it also is not using snap for updates.

My windows 10 pc is set to dark mode, my win 11 pc is set to dark mode, my firefox theme on both pc's is set to dark mode, my phone is on light mode. On my windows firefox which is updated on both devices the top bar will stay dark in dark mode (default firefox theme) but after certain pages it resets itself to light, is this because of my phone being on light mode and themes are syncing over? its extremley annoying and after using the debug: page to try and force darkmode i had to reset firefox due to debug causing issues, now im using an untouched firefox version and it keeps changing from dark mode to light mode!

The LastPass add-on has somewhat spontaneously stopped auto-filling passwords even though I have that option enabled. I assume this is a Firefox issue because my vault is there just fine and recognizes the website and passwords (just won't autofill). Has anyone else run into this issue? How did you resolve it?

When i select the "show all history" on the drop down history menu nothing happens. It used to but no longer does anything. Why not and how do i restore that feature so it will show me the History?

Sometimes, if the computer is offline and Firefox is open, when the computer goes back online Firefox can't connect to any website, with the page "Hmm. We’re having trouble finding that site.". The only fix is to close Firefox and open it again. Going offline doesn't always do this, and while I'm not sure of what exactly causes this to happen, a way to easily reproduce it is:

• Turn off the Wi-Fi;
• Reboot the computer;
• Open Firefox;
• Turn on the Wi-Fi;

After the computer is connected, refreshing the page sends you to "Hmm. We’re having trouble finding that site.". You have to restart Firefox.

A way that doesn't 100% reproduce it, but works enough times, is to reboot the computer without turning off the Wi-Fi, and open Firefox as soon as possible (before the computer manages to connect to the router, which is the part that isn't always consistent). Rarely, it happens after suspending the computer, or after a disconnection due to an unstable connection. I can reproduce it in Firefox's safe mode. I have a hunch that maybe this is related to networking drivers.

I'm using a Lenovo IdeaPad 5 14ARE05 (Network controller: Intel Corporation Wi-Fi 6 AX200 (rev 1a)), Linux NixOS 22.11 (I don't know about Windows).

Ask me for any log you might need.

This is kinda a duplicate of https://support.mozilla.org/en-US/questions/1078253, except that their solution does nothing to me.

Hello. I've had this problem for over a month now ever since I switched to Firefox from Chrome.

Problem: Every once in a while, Firefox will suddenly be really slow and not load a page. When it finally does load, all text on the website is in the first font alphabetically on my computer. (I tested this by adding/removing fonts on my computer to confirm it was doing this and not just loading a specific font. I have a lot of fonts because I'm a graphic designer, and it's always picking the first font I have when they are all listed in alphabetical order.) This problem can occur on any website.

When the problem occurs: I thought it might be occurring when the computer or Firefox was low on memory, because the problem happens a lot more often when I am working (and thus have lots of programs and tabs open) than just browsing. I started working with both Windows's Task Manager and Firefox's Task Manager open so that when the problem occurs I can check to see what is happening. Memory usage when the problem happens is kind of high, usually around 50-70%, with Firefox being the most or second-most memory-intensive task in Windows Task Manager. But no other programs on my computer are slowing down when Firefox is, and Firefox's Task Manager is not showing any one tab/add-on using more than "Medium" usage. (Although notably, the tab that is having the problem is not showing up in Firefox's Task Manager at all.)

What I have tried:

• checking and unchecking "use hardware acceleration" settings in Firefox. (It doesn't seem to matter, the problem still happens)
• changing the default font settings in Firefox
• closing and reopening Firefox. (This does fix the problem temporarily. After reopening Firefox and restoring the session, all pages load normally. But the problem will happen again later on a different site.)
• restarting the computer (I shut down every night and turn the computer back on the morning. This problem still happens almost every day and often multiple times a day.)
• Having fewer tabs open. (That does seem to decrease the chances of the problem happening, but it does not decrease those chances to zero. The problem has occurred with as few as five total tabs open.)
• Checking add-ons (I'm not using very many add-ons in the first place—uBlockOrigin, Don't Accept webP, I don't care about cookies, and AutoDelete Cookies.) All of them are showing no or low usage in Firefox's Task Manager.

I am running Windows 10, Intel(R) Core(TM) i7-9750H CPU @ 2.60GHz, with 16GB of RAM.

Has anyone else ever experienced this issue? Does anyone know how to fix this? I'm really sick of having to close and reopen Firefox in the middle of work.

When I upgrade Firefox versions, I create a new profile folder to test the newer version. When I upgraded to V101, I found Google Maps worked very well using the standard config file the install created, especially in relation to panning in Street View. then when I miggrated over my old config file from V88 Google Maps became very sluggish on panning. Clearly some config entries need tweaking. How do I know which class of config entries are used by Google Maps? I dont want to compare every single line of the config files..

Its about time Firefox came with a flyout when you hover over each config entry to tell us what it does?

I have been using Firefox as my default browser for many years and much prefer it to the other browsers. However, several weeks ago Firefox started blocking the download of my morning newspaper. Now I have to copy the link from my morning newspaper email and paste it into Chrome to get access to my newspaper rather than simply clicking the link in the email. While I found this very annoying, when I couldn't find a workaround, I just continued to copy/paste into Chrome. Today I tried to download my IRA quarterly statement and found Firefox is blocking this pdf download also. Note that in neither case does Firefox tell me that they are blocking the downloads and they just do not download and some pdfs do download. So this is now getting beyond just annoying. Is there a workaround for this new Firefox problem or is my only alternative to define Chrome or Edge as my default browser and give up Firefox?

Years ago I imported a Firefox profile from Ubuntu 16.04 to a PC running 18.04. It wasn't very hard. View Hidden Folders, find the old FF profile, copy it. Then go to the 18.04 PC, delete or rename the existing profile, and paste in the profile from the 16.04 rig. Restart the PC, Firefox came up on the 18.04 PC just like it did on the 26.04 PC.

But Ubuntu is doing something different now. Firefox is inside the "snap" folder. Apparently snap is some sort of new package mgr. (?)

I found a firefox profile a few levels down inside the snap folder: Home/snap/firefox/common/.mozilla/firefox/xxxxxxxx.default

Does snap complicate things? Or can I replace the new profile on the 22.04 PC inside the snap folder with the profile that I want to use from the 18.04 PC? Just like in the past, but inside snap rather than the .firefox folder in Home?

Firefox not responding when I open the mobile hotspot on my laptop. I'm not sure if the problem is the program itself or windows or my laptop, but chrome seems to be working fine when I open hotspot, so I thought Firefox has something to do about it?

For more context, I don't have wifi connection in my new apartment, but I do have ethernet cable connection. That's why when I do need wifi for my phone I just open the mobile hotspot in my laptop. When I do, Firefox suddenly crashes/not responding and I have to close it. Same thing happens with discord, but I only lose connection, it doesn't crash. Sure I can use chrome, but all my bookmarks are all in firefox.

This only happened recently, June 2022. I didn't have any problem the month before, I was able to use hotspot while using Firefox at the same time.

Anyone have any idea whats the problem and/or how to fix? Thanks.

Hello:

New computer; logged into Firefox; apparently synced; ... where are my bookmarks? I have purchased and set-up many PC's in my life. Why would this occur now -- for the first time ever for me?

I wanted to get an couple new addons to my firefox browser. But whenever I try to get one i get the message 'Installation aborted because the add-on appears to be corrupt' whether I save the file and install it in windows, or trey to install at the firefox addons page. I have done multiple re-installs of the latest browser, cleaned every file out of the system, even joined this community in case I have to get some kind of membership to get addons.

I am out of ideas to solve the problem, and I cannot find anywhere on the internet where the 'Installation aborted because the add-on appears to be corrupt'. problem I have is solved. Please help.

Good afternoon. My name is Tito, I had a lot of logins and passwords for the most of the sites saved in the firefox passwords. I went to another country for vacation and for some reason i lost all of my saved logins. Is there anyway to recover it. one of the advantages of having saved logins nowadays, and because all the passwords get more complex is to save it and in case we forgot we can always check it.. is there anyway i can recover it?? Thank you. best regards Tito

Comcast/Xfinity login appears and blocks use of Firefox. Asks for password .We do not have Xfinity. How do I get rid of it? Ihave MacOS Monteray.It also is blocking Safari.

My Bookmarks did not transfer over from either my prior Firefox browser or my Safari Browser. I could not find the bookmarks.plist for Safari, and the upgrade did not ask if I wanted my Firefox bookmarks transferred over.

Hi guys,

I'm trying to generate API key to access addon APIs using the addons.mozilla.org -> tools->Manage Api Keys.

As web screen states before generating the key I need to confirm it via email, however no confirmation email was sent to "[email address]". This might be relevant to the issue, the account email was changed from "[email address]" to "[email address]" some time ago.

We've checked the following link trying to troubleshoot the issue on our end, but had no success. We haven't found the way how to resend the email via UI.

Could you please resend the confirmation email for API key to "[email address]" once more?

Thanks in advance, Vladimir from Kaseya Inc.

Hello,

I'm using Firefox 102.0 (64-bit) on Win 10. When I click on the download icon of email attachments or Whatsapp files, firefox opens the pdf files in a new tab instead of downloading them. All other file formats are downloaded correctly instead. How can I correct this problem, please?

Best regards, Giovanni
