Firefox Community Forum

I'm really shocked that the developers at Firefox has not at all fixed the memory leak issue, which caused my PC to crash three times in a row. This is clearly unacceptable; even other browsers I use don't eat up a lot of RAM in a matter of seconds that ends up my PC lagging, or worse, crashing as a result. To the Firefox devs; why are you overlooking an ongoing issue that should've been easily fixed from the get-go, especially with updates that obviously have nothing to do with the memory leak issue? It's really easy to make such a popular browser not hog up memory so easily without causing so much lag, even on higher end PCs.

If the memory leak issue isn't fully resolved by greatly reducing memory usage, especially if I'm only using one or two tabs with me, I will have to consider seeking for another working browser that does not have a memory leak issue, and remove Firefox and never reinstall it altogether.

Was clearing out some files yesterday in the middle of taking screenshots on Netflix through firefox (per usual) when suddenly whenever I go into a netflix TV show I get the purple-green image down below that's all wrong and corrupted. Feeling especially confused because I can take screenshots anywhere else on other browsers or Firefox, even on the Netflix home page, perfectly fine - but this format below stopped working?? Am hoping to resolve the issue quickly cause one of my Favourite shows I wanted to post about is having a new season drop in like 2 days :(

A bit of background, I have been working on systems since the Commodore Vic 20, so I'm not 'new' or would typically be helpless as many are if they have system problems.

Over the last week I decided to format my Mac and re-install the operating system. I have a lot of graphics design that I will be doing for an unknown period of time. I have over the years collected many free fonts and I started installing them about 5 days ago. I don't believe my installing fonts wouldf have affected anything within Firefox, but Firefox is the only browser that I'm having this problem with. I checked Safari and google displays everything as it should as well; my graphics deisgn software forums are displaying fine. I have not used google for anything during the period that I was installing the fonts, so I don't know exactly when this started but yesterday I discovered it.

I tried going to the menu on the top right hand corner -> Help -> More Troubleshooting Info -> Refresh Firefox. I then went into MacCleaner Pro -> Clear Cache and Clear Purgable Data. Then restarted the machine. No change.

I then saved my passwords and bookmarks, then uninstalled Firefox using MacCleaner Pro and then went to Remove Remaining files.

Downloaded a new copy of Firefox and the problem still exists.

I tried changing the theme to others. Went to Settings -> General -> Language and Appearance. Set theme to dark, then back to automatic. Changed the main font from (Default) Times to Times New Roman and back to (Default Times) ... but still this problem exists...

Help... Please and thank you.

Hello Mozilla! For a few days, Firefox has been offering me a bad identifier when I fill out a form. It offers me my email address and now the address of a friend. However, neither of them appears in my automatic filling data of my preferences… and therefore impossible to remove it! Can you help me please? I can't find the right answer on the forums… Thank you very much to the whole team for this great work that you do.

Since installing the latest version of firefox all the web pages are in dark mode even though everything is set to light mode in settings and themes. A lot of the sites are not designed to be in dark mode, they look horrible and some buttons/text are not visible unless the mouse is hovered over them. Strangely these support pages are the only ones in light mode. Please help

v114 tested works fine, and probably alot of versions after but not the last few

I stopped using Firefox because of the level of BS Big-TEch involvement and lack of PRIVACY. I've been using BRAVE. But they are'nt much better. So I'll switch between as I feel fit. Just so you know. My recent irritation is Shortcuts. I like the speed and convenience of CHOOSING & USING my shortcuts.

I do NOT like the option of "sites you save or VISIT" That is NO option. I DO not want YOU choosing to save every site I VISIT and loading onto my screen. This is not a choice. Just because I visit a site WHY do you save it to shortcuts? It's a PITA deleting crap I don't want.

You should ONLY save the sites I CHOOSE to add.

Not rocket science. WHY DO YOU CHOOSE TO DO THIS?

The Internet It's becoming less and less about what I want to know (Trying to get relevant search replies is harder than ever) and more about what you want to know about me.

MALWARE ? When you are collecting more data than you know what to do with it is Oppressive.

I can see my current usage of Firefox being cut short again at the point of annoyance with this parasitic tech.

Oh and the proccess of creating an account and passwords blah blah just to ask a question that changes sweet FA...... No wonder there's anger. Idiots.

Since a few days now my URL bar is too small. I can see where it used to be in light gray, but the text box is just a small part of it. I searched everywhere but I can not find anything to fix it. I even tried to reset the settings to default but it is still the same. Any idea what I can do?

Here is a screenshot of how it looks like when I click into the text box: (see attached)

I've been experiencing issues with my firefox browser (most updated version 129.0.2, running on Mac Sonoma 14.6.1). Seemingly at random times, it decides to start displaying weird symbols all over. The settings, the menu, the text on webpages, it all reverts to these weird symbols. Restarting the app and my laptop works sometimes, but only for a little bit of time then a day or two later this starts to happen again. I've tried to look at other help articles but it doesn't seem to be a font thing, it's becoming really frustrating and I hope there's an easy fix otherwise I won't be able to keep using this browser as I share my screen for work often.

Firefox will not load. I receive this message: Error: Platform version ‘130.0’ is not compatible with minVersion > = 129.0.2 maxVersion < = 129.0.2

I cannot use Firefox due to this error message. What do I do now?

I cant log into x.com. Whether tracking is set to strict or not. I just get the same error. I have tried re-starting my browser and computer. I currently have it set to strict and have it turned off for this site. Why cant I go to this web site?

Hi again,

so, in my other question I was reminded about Browserleaks and while I was there testing TLS I also tested Canvas and it said 100% unique which I was surprised because I have the Enhance Protection in FF in "Custom" with both fingerprinting options selected and in "in all windows", plus CanvasBlocker.

100% unique is not good, right? That's what I thought at first. But then I remembered, CanvasBlocker rotates settings all the time, so even if my fingerprint is 100% unique it's also changing all the time which means "they" can't identify me (supposedly). Then I also thought "actually it might be better than not 100% unique because in that case I might have more issues with websites thinking that it's someone else trying to access my account". But then I thought "although if it's 100% unique changing all the time it's also like if it was a different person".

I deactivated CanvasBlocker and tested again and it was also 100% unique. Then I reactivated CanvasBlocker and I deactivated FF's anti-fingerprint. Again 100% unique. In other words, I don't see a way to see what is the difference between using CanvasBlocker on top of the native FF anti-fingerprint. That's where you can help :)

So, questions.

1) can you tell me what exactly does FF block about fingerprinting? And, does it rotate settings like CanvasBlocker so that this "100% unique" is not actually a real issue because it's different every time? Or is it a bad kind of 100% unique in that case?

2) what would create less issues of websites thinking that I am not me? A rotating 100% unique, or a not 100% unique (in which case, how to I achieve that, considering that neither CanvasBlocker nor FF's anti-fingerprint nor both together can do that?).

Would you say that having a VPN with own DNS which block tracking on a domain level, plus AdGuard with all possible filters, plus FF's Enhanced Protection in "Custom" with all at max, plus CanvasBlocker, is a good combo? Or what could I improve to reach a good balance of not being tracked/fingerprinted, not being blocked "because I am not me", reasonably light resources usage, and reasonable browsing speeds?

I used uBlock Origin previously because it's lighter on resources and it triggers my laptop's fans much less than AdGuard but it doesn't block (not even with element picker) some annoying things of websites that I visit often. In case you wanted to recommend that :)

Thanks!
