When I run Firefox on Linux, the window initially starts at 1260x720 size. But when I try to maximize it, then the Firefox window size gets much larger than my screen's resolution. The maximized size is 2800x1600 size, my monitor is 1920x1200 only.

I tried different versions of Firefox and noticed this new behavior started with version 73.0, while it worked fine in 72.0.2 and versions before it. I even tried 73.0b1 and it has the issue already. I see the same exact issue when I tried the latest version 108.0.2 as well. It seems like something got broken in 73.0 unless I'm doing something really wrong.

Not sure if it makes the difference, I'm using MWM window manager on Linux. Please advise.

"I've been experiencing an issue with Mozilla Firefox where it doesn't display the Silver Taxi Sydney Silver Taxi Sydney website correctly. Other websites seem to load fine, so I'm wondering if anyone else in the community has encountered similar problems with specific websites on Firefox. Are there any known compatibility issues or common solutions that could help resolve this problem? Your insights would be greatly appreciated!"

Windows, Ver. 120.0.1, 64-bit. Hardware acceleration enabled.

Many tasks on all websites result in GPU usage spikes. Very basic functions such as page scrolling or entering text often take a half second to register, making the browser feel unresponsive. I do not have a bunch of tabs open either and am not using any other applications that would be power-intensive.

Using an RTX 3050 Ti Mobile. Newest NVIDIA drivers, 546.29.

GPU usage spikes to over 10% when just scrolling the screen. Help!

I've been unable to play amazon prime videos on firefox for some time now. It comes up with error message 'video unavailable'. I've followed all the advice on amazon website and google searches but nothing works. what do i do ? (this is on asus zenbook laptop) I've tried checking for updates on firefox and add ons, restarting Firefox, restarting laptop, clearing cache , checking DRM settings and deactivating proxy servers.

System Software: Win11Ent_x64 v22H2 (b: 22621.2283) MFF v18.5.0.0

No matter what I try, my MFF keeps crashing at startup. For some reason, it tries to open 2 pages the windows at the same time, which is illogical. I deleted firstly my: sessionstore.jsonlz4 logins.json to no avail.

Then I tried to open MFF through elevated CMD with the command: C:\Program Files\Mozilla Firefox\firefox.exe -safe-mode Again, 2 windows pop crashing immediately.

I do not understand why all of the sudden, it tries to open 2 different instances at once. This makes no sense. I am out of ideas, having tried many an option found on Google, but which none give me a solution.

If anyone has an idea, I would be quite darn thankful. This MSEdge crap that I need to use now is not quite my thing.

Thank you. Ke'Ylan

Alright first of all I already tried all the tipps about Proxy and basically anything network related. It also happened out of nowhere since I was using my computer the night before but when I tried opening Firefox the next day it wouldnt load any site, crashed if I tried too much or got really weird and even if it did load after a long time of trial and error it only lasted for a bit and didnt load fully either. I'm on version 108.0.2 as of the last time checking. Everything else seems to be updated as well especially since other browsers work perfectly fine. I also cant really click on much since as I said if I try too much it crashes or doesnt work as intended. I'll provide some pictures which might help the cash report just in case.

I'd also rather not try reinstalling everything since I have a lot of rather important tabs open and I dont wanna risk losing any of them since im not sure how well the Firefox sync. works in this case.

I have recently reinstalled windows and then installed Firefox. When I go to settings then click on an item Firefox freezes.

I have uninstalled and reinstalled (with revo uninstaller) but it still happens.

Would appreciate suggestions.

I have just reinstalled windows and then Firefox. If I click settings then a menu item it just freezes.

I have uninstalled and reinstalled.

Using Windows 11 Pro 22H2.

Any suggestions?

Hi,

I'm getting errors when trying to make online card payments with Firefox. Things like, Invalid card number, not being able to type number in box provided, (No Cursor). It works ok on some sites but not others. However, if I switch to the Edge browser all transactions work perfectly. This has been happening for some time (Windows 11). I'm thinking this could be a bug but not sure.

I use Firefox for Mac. Often when I want to click on a link or complete an on-line form, a long list of unwanted suggestions pops up and orevents me doing this. Only by hitting Escape can I get control back.

By the way, I don't want any solution which involves clearing the cache, as I value that help.

As of yesterday when I was running v119.0 I was able to screen capture streaming content from Hulu/Netflix etc, this morning after upgrading to v120.0 overnight, that capability is now lost. Video and still captures are just a black screen. Please fix!

Hello, I have been a diehard Firefox user since it was still in Beta. I have been using computers personally since 1994 and professionally since 2004, doing Windows and Linux systems administration. I can and will do whatever (within limits) you need me to do to troubleshoot and resolve this issue, which is otherwise going to cause me to abandon this otherwise excellent browser, perhaps forever. The browser.cache.disk.capacity seems to work, but browser.cache.memory.capacity does not.

Why does firefox not respect the assigned values for browser memory cache (browser.cache.memory.capacity)? Is there anything I can do to limit the memory and processor usage of Firefox and its child processes? Is extension CPU/memory usage constrained by the application values? Is there a way to determine and/or limit the resource usage of extensions?

I have included a number of screenshots documenting its behavior and generated an about:memory report during "normal use". After configuring a number of system variables, I then attempted to determine its resource usage under heavy load.

Open the browser with a couple 2, 3 tabs: ~1GB memory usage Use the browser as "normal" (dozens tabs): ~2GB memory usage Open 100+ tabs from history: The CPU and memory resource usage increases until it consumes all available system resources despite configured values. After killing and restarting the process, the tabs have invisible titles in the extension and browser, and must be closed using Ctrl+W until only a few remain after which the browser can be used normally and again consumes ~1GB.

While I understand "just don't open so many tabs", under some circumstances such as poorly written websites, bugs, etc, even single sites may attempt to claim excessive resources. I sometimes run VMs and such on this machine and in order to retain a responsive system, cannot have applications consuming all of the available resources. I have found one proposed solution that uses an external application, is this the only way?

I am open to allowing Firefox to utilize more of the SSD storage (the 1GB limit was imposed for testing) and would be fine with increased slowness due to disk cache or refetching internetworked resources. However, none of the settings I have changed or attempts I have made appear to be able to limit the memory usage in any way. Additional included screenshots are linked above instead of as attachments due to number. I can share or generate additional reports to assist in troubleshooting.

Thank you! JackD

I have updated my Firefox on PC to the newest version available (version 120.0.0.8720 as of 24/11/23 00:30 UTC). Unfortunately whenever I try to open it, it loads a blank screen and then crashes, and brings up the crash reporter. This has happened every time I try and open Firefox, even during Troubleshoot mode. I have over 180+ tabs and thousands of bookmarks on my account that I do not want to lose (I have not used Refresh Firefox for this very reason) but if I can't even access them on my computer then what can I do?

Please help me, I want to know how to fix this and keep my tabs and history. I am desperate.

Hello,

I have been using Firefox Mozilla for many years. This morning it opened up fine. Then this afternoon (Dec 7, 2023) it would not open for me and when I try to open a new tab it says that it crashed.

I looked and I do have Firefox as my start up browser in my settings. Thank you for any advice on getting back to my favorite browser.

Sincerely, Sandy

Hello! I need some help. Every since 4-6 months ago, Firefox has been extremely slow when I boot it up at first, with some page load times taking more than 10 minutes. Some fixes have seemed to work, but they never work permanently. From my testing, it is not the result of any extension and the issue persists in troubleshoot mode. What has not helped my testing is that, after enough restarts of Firefox, the problem goes away and web pages load quickly, so this has caused some false positives. Has anyone else had a similar problem they were able to fix? Should I try uninstalling Firefox and reinstalling it?

Firefox use a lot of CPU time ( it reaches 100% ) while watching youtube videos in 720p on Windows 10, and videos lags and stutters too much. Not using any ad blockers, non of plug-ins are on. It does work just fine on Ubuntu on the same machine Vids also were working fine on previous popular web browser known for its spyware

Using hardware acceleration is on in browser settings. Specs are: CPU: Intel(R) Core(TM) i5-3230M CPU @ 2.60GHz 4,00 GB x64 Windows 10 Home edition 22H2 GPU: NVIDIA GeForce GT 635M

I tried to pay my Wells Fargo VISA bill online as I do every month. This morning it listed all my accounts correctly on the 'Accounts' screen, but when I clicked the options to transfer money, depending on the screen I was on, it gave a message "you do not have two accounts to transfer money from and to" (not the exact wording.)

I tried to use a different path to do the same thing, and on that screen it displayed the 'FROM' accounts correctly but the "TO" account area was blank.

I had to close Firefox, load Edge, and was able to transfer the money from the checking account and pay the VISA bill.

This has never happened before and I have done this transfer and pay operation every month for years. Something has changed in the browser and needs to be fixed.
