Firefox Support Forum

Firefox keeps crashing randomly, sometimes at startup, and sometimes just in the middle of a session. Sometimes just one tab will crash, and other times it'll be the entire browser. I ran it in troubleshoot mode and it still crashed, so it's not caused by an extension or anything. It never used to do this before and I don't understand what's causing this issue.

Dear Firefox

                                                      SEASONAL GREETINGS

Just about a week ago after my last Firefox upgrade, the browser started weirdly. The style, characters, boxes and bands were abnormally changing sizes. I tried using Firefox settings: Zoom all to no avail. I went into System display and did advanced scaling and it was of no help. I further went on System Restore and Resetting my computer and it was all the same.

I removed all add-ons, cleared both Firefox and the Systems Caches and carried malware clean up of my computer. I also carried out troubleshoot and the computer informed me there was no malware in the system using Windows Defender.

After carrying out any the above when I restart the computer all the values change to their abnormal values with very large Firefox Interface, the bands and spaces including the URL address bar appear abnormally large. When I use the mouse, sections of the browser moves all across the page uncontrollably. This happened for over a week. Hence I could not access my AOL email.

Though risky as you advised against, I had to download a lower version : 82.0.3 which appears to steadier and then managed to access my email and other apps, like YouTube, Facebook, Twitter(X), etc.

Within this period I had the same problem with my second preferred browser - Yandex. I contacted their Support Team and explained to them what was happening. They asked me to send screen short the problem. I took the screenshot and found out that in the Interface at the top the size was shown to to be 66%, but yet the band spaces and characters were abnormally large.

They wrote back thanking me with the advice to open browser://flags in their Yandex browser, and there disable "Enable 125% scaling factor" option by selecting "Disable". When I carried out their instruction, just like magic, the Yandex browser returned to normality.

Firefox, do you have such a function so as to advice me? You probably would have to get your developers into this matter. My honest opinion is that Firefox is rushing out hastily with upgrades. Hence the problems. On the Internet there are many complaints about the instability of Firefox.

Thanks in advance in hearing me out.

Not sure the best way to describe the issue, but it seems like Firefox is not able to or doesn't clear memory when streaming Hulu for a while. It just slowly accumulates memory usage and eventually just hits a point where the tab crashes and doesn't continue until you close and reopen the site.

Is there a way to mitigate this or is it a known issue where it can't clear memory?

I have 32GBs of ram (about half occupied system wide), but Firefox appears to cap out globally between 7 and 8GBs, then Hulu freezes, forcing me to close the tab and go back to its home page.

I am a bookkeeper and use QuickBooks Online (QBO)(AUS version) as my preferred accounting program, Intuit recommends using Chrome, but I had problems with that too, in that it has fields in QBO that will not work, I have switched to Firefox because it handles the 'black' look and the columns within the ledgers are more stable, however Firefox is constantly crashing it can recover most times to where I was, but it is most infuriating. Question is, is this a known problem and can it be fixed by changing the settings? Geoff Woodford

Characters dissapearing, missing, garbled only in Firefox. Seems to be ok in troubleshooting mode. This only happens in Firefox so it appears to be isolated. As you hover over links is when it happens the most. I have the latest version installed and was just loaded on a new system.

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 recently updated Firefox and now I'm getting a noticeable stutter when playing back videos. I used to have this issue when I first got my steam deck so I installed a flatpak ffmpeg-full which fixed the issue completely but a recent update I installed has brought the issue back. I uninstalled and reinstalled the flatpak and restarted my device but the issue persists.

Hi,

I am using Firefox Version 122 on Windows 11. For the past month Firefox is slow to start on its first start. It took 2 to 2 1/2 minutes to load up. I have tried ways to fix it but not working. I tried using Google Chrome to test the speed and on the first start and it takes 5 seconds to load up. Therefore, it is not my computer problems. Please help.

Thank You

Firefox has been white-screen blocking my access to some common websites including CNN, Amazon and possibly others. No error messages, just a blank white screen. This is a sudden change and has never been a problem in the past. Chrome and Firefox on my other computers are not affected. I have cleared caches and deleted all tabs with no change in symptom. I've also checked CPU and memory resources and both appear normal. No sites are being blocked by settings either, though I would expect Firefox to give me a "This site is blocked" message of some kind if that were the case. How do I fix this?

Here are the three latest crashes report ID's bp-22fa9148-cb5c-4b8a-ac02-575990240215 bp-1ac0f4d4-e821-4ff8-ab9c-801fb0240215 bp-023f768b-7f66-4a51-862d-3934f0240224 If anyone has any experience with reading these crash reports and can help me figure out what is wrong that would be amazing!

Whenever I start Firefox it loads up on the upper left corner in a minimized version and I have to double click the maximizing button to get everything right. I tried the tip of deleting the .js file in the Profile folder of the browser. I did that 5 times and the problem still occurs. Everything is up to date. What's wrong?

Hello, I have an HP laptop 250GB, (sticker saying intel CORE i5 inside) that is now practically un-usable, virtually every action gets a Firefox is not responding, the cursor is slow to respond and keeps dropping and then when a page eventually opens, when I try to use the cursor the page disappears. I am not good with computer terminology and just want to use the basics. After approx 2 years from purchase and the slowness, I went back to an old laptop at the beginning of 2020 which I have very little trouble with, but it is failing slowly and have been trying to get the newer one going again, but I get so frustrated with the waiting and mostly get nothing done. I don't know what else to add. I gave up paying for service, I am just told it should not be that slow even right from new. I knew that already. My son visited at Christmas and said the processor is running at 100% all the time. Thought it maybe a faulty processor. Ian

I use Mozilla as my browser on Windows 7. When I click on Mozilla I get an Error page which reads, " Server Error in "/" Application. Runtime Error. Not sure how to fix this. Can you help. Thank-you

I have constantly crashing tabs with FF 121.0.1 32-bit on Debian (happening since at least 120, and probably 114 or perhaps 115 ESR), and about:crashes has no listing of any tab crash reports; this hasn't been an issue until the most recent version. I'd like to report them so that they could hopefully be fixed, but reporting doesn't seem to be happening? Thanks.

Stuck with this hourglass logo on tabs since the latest update v121.0

Now what I have noted is that this is causing the pages to load slow. Only ublock extension is installed, tried all dns settings but the result is the same. Is anyone facing the same?

These pages say to change the value and this hourglass thing will be removed

But I cannot see any option to change the value on that location

What to do now?

Hey Mozilla Support Community,

I hope you're all doing well. I'm reaching out because I've encountered a bit of a head-scratcher and was wondering if anyone else has experienced something similar.

I recently got myself an Intel Evo laptop, and while Chrome seems to be working seamlessly, I'm facing compatibility issues with Firefox. It's a bit puzzling, and I'm hoping to get some guidance from this knowledgeable community.

Here are the details of the issue:

Problem: I'm experiencing compatibility issues between Firefox and my Intel Evo laptop. The browser doesn't seem to be performing as smoothly as expected. Oddly, Chrome is working perfectly fine.

Symptoms:

Laggy performance when navigating websites. Occasional freezes and delays. General sluggishness compared to Chrome. What I've Tried: I've already tried a few troubleshooting steps:

Cleared the cache and cookies. Disabled unnecessary add-ons and extensions. Updated Firefox to the latest version. Checked for system updates on my Intel Evo laptop. System Information:

Firefox Version: 50 Operating System: window 10 I'm turning to this community in the hopes that someone might have encountered a similar issue or has insights into resolving compatibility concerns between Firefox and Intel Evo laptops. If you have any tips, suggestions, or if you've successfully addressed a similar problem, please share your knowledge!

Your help is much appreciated. Thanks in advance for your assistance!
