Firefox Support Forum

First, this post is basically Congratulations for Firefox upon working almost flowlessly under this extreme heavy load without crashing. Saving/loading sessions works well. (which is unexpected but makes me _very_ happy :-)) Firefox exits properly without any exceptions, no matter how long it runs, or how many times the PC is sent to STR mode meanwhile.

Second, everything is fine, except RAM usage. No matter how many RAM is installed, Firefox takes up all of it after a few days of normal operation. I have recently upgraded my PC from 16 to 24 GB of RAM only for this sole reason to see if anything changes, but it did not produce any noticable change, except that it takes 5-7 days for Firefox to fill up all the RAM instead of the 3-4 days before. Disk space on C: drive was nullified by Firefox as the paging file went up to 50 GB.

I want to hunt down this thing. I have approx. 300 tabs, 2 addons, and Hardware Acceleration is disabled since otherwise Fox hangs several times a day (have to be killed from outside). Pics are attached. https://addons.mozilla.org/hu/firefox/addon/tree-tabs/ https://gitlab.com/kroppy/TreeTabs

I'd like to get suggestions where to start.

1. Disabling or replacing the adblocker ?
2. Inspecting memory usage on Process Manager (about:processes) and Task Manager (about:performance) pages ?
3. Installing some external tools like Firemin ?

Please don't suggest neither safe mode nor disabling all addons, since that makes it impossible to reproduce this amount of load, which is the primary reason behind the symptom.

I PrtScr'ed Process Manager and Task Manager, see that RAM sizes per page are normal in Task Manager, but not in Process Manager (10 times more).

CPU usage is totally normal for this load, even when memory is in the heaven. See the TaskMan pic. (I suppose that's because of ad blocking)

Thanks for any ideas,

Peter B. (I'm PC enthusiast)

-- Windows 7 Ultimate SP1 64 bit Firefox 106.0.5 (latest autoupdated) no firewall nor any antivirus - since 20 years with no infection ... AMD FX-6350 Six-core ASUS M5A99FX PRO R2.0 24 GB DDR3 1600 MHz Sapphire Radeon HD 5750 1GB (AMD Catalyst 15.11.1, Nov 18, 2015)

I am currently having problems with my Firefox browser. For example often if I type something into the google search box at the right of the address bar and hit return nothing happens until I go down and select Bing instead of the google setting. Also in hotmail (I am on a desktop) if I go to reply, the original is now ether twice. This does not happen if I use Google browser. But I prefer Firefox as I have used it for years.

My concern is if I delete Firefox and reinstall it, I may lose some of the settings or bookmarks that I have set over the years.

Any suggestions? Please simple as i am old and not computer savvy.

Your help would be so appreciated. I am currently on Firefox 107.0 (64 bit)

Thanks, Anthony

After moving to Firefox 91.9.1esr I found problem with System theme 1.2. The color of tab add button was changed, and the button is not visible with my Windows 7 classic windows system theme. So, I'm trying to find a way to port System theme 1.0 color scheme to newer firefox versions.

Creation of a simple theme with firefox color extension works. But it is unable to recreate the effects related to active and inactive window color changes. As, I had to use bitmap to get the OS blue color transition pattern.

It seems the system theme is stored in omni.ja file. Modification of the omni.ja seems to be not a practical solution. So, it would be a better way to create an addon theme with the same code as the System Theme 1.0.

The first question is, if it will be possible to create a theme with the same code as a system theme has. Will it be able to perform the same way?

The next question is: Where the source code of the system theme is? I was unable to find it in the Firefox source. It seems, it is not stored in any obvious location.

After the second to the last update to Firefox I started experiencing an information pop up message "Could not determine any profile running in backgroundtask mode!".

Is there a fix for this?

Thank you.

Hi

The Arabic font broken on Facebook after reinstalling snap version of Firefox 107 on Ubuntu 22.04 given that the font on YouTube search look fine (but not on Facebook). I tried to reinstall Firefox in multiple ways like using the deb version reinstalling the snap one removing the .cache folder and logging out of the session and even rebooting my PC.

Why is my firefox is broken?

what is the solution ? it would be really appreciated

Hi, we have 4 PCs (3 running Win 10 and one Win 7) which updated themselves today and lost everything. Settings, add-ons, bookmarks, shortcuts all gone; looks like a new install. I checked the other threads and the profiles; there is only one profile and no backup. How to get my stuff back?

Hello :)

I'm using Firefox 107.0 on macOS 12.6.1 and I'm having weird issues with the displayed font. It appears on the startup screen of Firefox and on websites (see screenshots attached).

The garbled font is called ".SF NS".

I've tried turning the option "Allow pages to choose their own fonts, instead of your selections above" on and off without success.

I have also tried enabling and disabling hardware acceleration - also without luck.

The issue does **not** appear in safe mode. Unfortunately resetting the theme and disabling all extensions hasn't helped either :(

I have also downloaded and installed a font called "SFNS Display" but the issue persists.

Uninstalling Firefox (with AppCleaner) and reinstalling hasn't fixed the problem.

I don't know what else to try. Can someone help me please? :)

when opening tickets in our helpdesk system, TeamDynamix, the new window opens on the main display. if the Firefox browser is open on another display the new window has empty space on the right and bottom (see attachment). if the Firefox browser is open on the main display or the new window opens on the same display as the Firefox browser there is no empty space. dragging the new window from the main display to the display with the Firefox browser open the empty space disappears and the new window displays correctly.

this only happen recently. with an older version of Firefox (not sure which version), there was no empty space on the new window.

Firefox Version 107.0 (64-bit) Windows 11 Version 21H2 (OS Build 22000.1219)

I can't open amazon.com. I've disabled my antivirus and have tried in 'troubleshoot' mode. I have cleared my cache. I have flushed my DNS. It's been going on for days. I keep timing out. Other sites do not exhibit problems. Chrome DOES open amazon.com quickly.

If I open multiple browser windows, each one moves about 1/4 inch to the right of the previous browser window. So if for example I opened 12 new browser windows, the 12th one would end up about 3 inches to the right of the first one. This is most annoying. How do I get each new browser window to open in precisely the same place as the previous browser window already open?

Any help would be much appreciated.

When I download images from some sites, they're in MS Edge HTML format. Is this because the site dictates this, or is Edge somehow interfering in the download process? I've disabled Edge on Startup. Can anyone help?

I tried to log on to FidelityCharitable.org which I have done successfully before. When I do, they give ma a message "We are currently aware of an issue with some 3rd party browser plugins that are causing issues with access to the Fidelity website. Please try running your browser in incognito mode - or using an alternative browser as we work with the 3rd parties to resolve the issue."

By the way, I still have an issue logging on to PayPal with Firefox too.

The Browser is gone completly basicly. I opened a "few" Tabs and then it suddenly crashed with my PC. Now My PC is getting old so Crashes aren't new but after the Restart of the PC Firefox just didn't work, it would Open but that's where it ends i can't access anything it doesn't react to any inputs, it's black screen can't even see my bookmarks it doesn't open last opende sites or anything altough i can Input somehting in the Hot bar but it won't react to it and just try to google it but that won't work as well. I installed a second version of Firefox now but for example my passwords.. not all of those were saved somewhere else. So if someone knows a fix for that or to just get them another way through files along side my bookmarks that would be very helpfull. thankss

I recently switched to WordPress for site hosting, and set up their Titan email. It's worked fine for the first couple weeks, but yesterday after I did a routine clear cache and cookies, my email became a blank white page. The URL looks correct. Have spent several hours with WP help to no solution. Email works fine in Chrome, and all other WP functions are fine in Firefox.

Je souhaitera que FIREFOX s'ouvre automatiquement en plein écran sans avoir à utilise un raccourci clavier. J'ai cherché dans les paramètre (general/accueil/recherche/vie privée/synchro...) sans trouver. Merci pour votre aide.

Hello! I am attempting to speed up a box office process by using a UIC card swiper with our ticketing software (which runs in-browser).

In non-Firefox browsers, the card swiper, when used, puts card numbers and expiration dates right into the necessary fields to save me time from typing them. Firefox (my much preferred browser!), however, reads the swipe as a Find In Page request, even when we're clicked into the text field where the card number is meant to go.

Does anyone have an insight on how to make this work the way it does on other browsers? Thank you!

I am looking for a way to enable Firefox to copy and paste PNG images with transparency. Right now, copy/pasting a transparent image replaces the transparent areas with solid black. This feature works as expected in all other mainstream browsers (it's something I use a lot in my workflow as a graphic designer for a website).

This bug has existed for a while, I'm hoping by now there is at least one extension that fixes it, or some kind of workaround. Thanks to anyone who can help.

I access multiple sites under a single domain:

https://my.domain/site1 https://my.domain/site2

Each site has a login, and the same account name (e.g. 'me') is used for each site, but with different passwords. I must use the same account name for each site.

As far as I can tell, the password manager will always truncate the full site url to just the domain name when saving the passwords, so both sites are saved to the same entry.

The password entry edit function does not allow one to edit the URL associated with the site.

Is there a workaround for this? Thanks, Diab
