Anyone else having an issue with the newest firefox in Linux Mint? I don't know what's causing it but when multiple tabs open my address bar and all other primary buttons/icons (including the menu button) don't work, only the download button. Across multiple tabs. Not using any groupings/classifications or any "new" tab features or vertical windows etc.

While running Firefox on MacBookAir with macOS 15.7.2 to browse simple websites I keep getting the below warning message. I may have 2 or 3 other apps open (like Apple Mail, MS-Word, Preview). "Heavy memory usage You're running out of memory and your Mac may become noticeably slower. Consider quitting some applications. Firefox 2,48 GB" So I quit Firefox to re-open again and continue my work. Does somebody has an hint where this message can come from ? Any settings to change on my MAC ? Thanks for helping

What causes Firefox to freeze when two video windows are opened, i.e. in a new tab, the video windows immediately start to freeze? I use Windows 11. Other browsers work fine, only Firefox freezes with two windows open.

Hi I always use Firefox on my Apple I-Mac and it has always been excellent but in the last couple of weeks a window pops up to say that Dashlane is slowing down Firefox when I am trying to type in E-Bay. Not yet seen it in any other situation but it it virtually preventing me listing items for sale on E-Bay. Always have Dashlane open on Firefox whenever I am using Firefox/the internet. Today I reinstalled Firefox but it is still doing it. Help please! Kind regards Jeff Worth

I have an issue where my firefox freezes whenever I try to take certain actions inside home assistants music assistant. I have created the following profiler of the issue https://share.firefox.dev/4pPZRPo

I have tried all the recommended settings to mitigate these kinds of problems (remove hardware acceleration, set disable all addons). I don't know where to report this exactly, but I'm hoping someone might be able to see something from the profiler that could illuminate what exactly is going wrong?

Notably this issue does not happen in firefox private mode.

Why does Firefox's hardware usage, especially memory (RAM) and battery consumption, have to be so high that the laptop fan noise causes a lot of noise in the environment? Windows 11 25H2

Firefox has been my entire family's browser of choice for as long as I can remember. Which one am I supposed to use now that Firefox won't quit shoving bloatware and diminished performance at me? I'm also seeing articles stating that they plan on making it even worse with more AI. I'm supposed to let them steal my data and turn my browser into sludge with absolutely no benefit to myself? And they're asking me to donate to them on top of it???

Does anyone know of a viable Firefox alternative that isn't a chrome dupe?

Having heard the news that Firefox's latest CEO wants to turn it into yet another AI-slop browser, I came to this forum to give feedback as an avid Firefox user over the last 4-5 years. I can see I'm not alone either; there are tons of other users who seem to feel the same way I do.

This is a very, VERY bad decision. So far, every "AI update" that has already hit Firefox has done nothing but make the browser worse and more inefficient. A few months ago, Mozilla was getting hit by complaints from desktop users about memory usage skyrocketing due to the implementation of an AI chatbot into Firefox. Now they've added AI search engines among other things. And surprise, surprise--no one seems to actually want to use these features. Why should we, if all it does is make computers run slower, overheat, and doesn't actually answer any useful questions or contribute anything meaningful?

I'm baffled at Mr. Enzor-DeMeo saying he wants to go all-in on making Firefox an "AI browser" with his whole chest in the SAME week that Microsoft has had to lower their growth targets for AI-related sales, some of them up to 50%, because NO ONE seems to actually be buying AI products. You know, on account of (you guessed it) not finding them very useful.

Other people have already mentioned the myriad of other problems with AI too, so I won't touch on those too much, other than to agree that AI is a plagiarism machine that's doing serious environmental damage. What I WILL say is that I personally have been using Firefox all this time specifically because it's avoided the AI craze as much as other browsers, or at the very least, avoided making it "opt-out" instead of "opt-in" to the same degree. But if this changes in the near future and Firefox does become yet another inefficient AI slopfest of a browser, I may seriously rethink my loyalty to Firefox and switch back to Chrome instead. After all, there would be functionally no difference between the two browsers anyway!

Please rethink this decision and consider actually listening to user feedback going forward. If Mozilla actually wants to retain their userbase, I'm sure I'm not the only person thinking about dropping Firefox for Chrome in the future.

Hi. Not sure how to tag this. I've turned off as many ai features in Firefox as I am able. I'm practically begging for this company not to add more. It slows the browser, it wastes energy, and to be honest? I don't want summaries of things I'm looking up, I don't want to be recommended apps or features, or chat to a bot, or have my sentences finished for me/help with writing beyond spell check. Google had a decent spelling and grammar checker and then they added gen ai garbage and now it sucks! PLEASE stop adding ai features to Firefox. It makes browsing impossible.

Please stop adding AI to your browser. It is making it slower and is a data privacy concern for me as well as many others. If you do not remove them I will be switching browsers. AI is not only bad for the environment, it does not even do the features you want it to do correctly. Please remove AI from firefox, i have been using this browser for years and would hate to leave because you refuse to remove AI features nobody asked for.

I can complete the sign in and enter my password, and then I get a spinning wheel and can no longer click on the tabs or minimize the window. I have to force close it and it shows as not signed it. I've also tried signing in using my phone and the QR code, same thing. This happens with or without 2FA, I turned it off and the issue persists. Everything else about the browser works completely but I can't sync across devices without the Mozilla login working.

So out of nowhere, I can't use the back button, or delete pages by clicking the 'x. I can't even click on the settings icon, or any icon on the menu bar. When I hover over any web page title, it shows a small window of it, but I can't get rid of it. I didn't change anything, so what's going on?

By addressing the problem that I have typed above. Why for over a year have I been getting 'Firefox not responding' message? I then have to start again every time. Thanks

The minimize, maximize, close line at the top of the screen is missing when Firefox opens. If I click the Firefox icon in the task manager to minimize it and click it again to maximize it, then the missing line at the top appears. This has been an ongoing glitch for a week or more. Perhaps you can fix this minor problem?
