I often keep many tabs open for research, and Firefox memory usage grows significantly over time. Are there practical settings or habits that help manage memory without sacrificing usability?

Hello All,

I'm using Firefox (149.0.2 snap) with LUbuntu 24.04.4 LTS. Because of a wrong graphic driver, I had to turn off hardware acceleration in FF.

When FF is started the Initial "Firefox - Choose User Profile" is unreadable (see attached : wrong_screen.jpg), but if I continue (click somewhere in the window) , all the opened tabs are readable.

Once in FF, if I want to select another profile from the application menu -> .. -> manage profiles, then the "Choose User Profile" window is fine (see attached : good_screen.jpg).

I tried to start FF with the "-P" option to specify wanted profile but it continues to start with the unreadable "Choose User Profile" window.

Could someone give me a solution, except finding the good hardware driver for my computer?

Thanks Bouilla.

When loading some pages, after the latest update to Firefox, I noticed that many websites started, loading slowly or waiting for other content requested by scripts to time out before continuing to load the content of the page. Some taking 20-100 seconds to throw an http error/timeout in the network tab. I even tried it having all my extensions disabled, vanilla FireFox and I still have the above issue.

The only fix I have now is using uBlock or some other plugin to block the url's of resources that are not loading or have been timing out. One such website/url being cdn.cookielaw.org has been the worst making it seem like some websites were straight up broken and unable to load.

Anyway I have fixed this issue by doing the above and blocking the urls of content that doesn't load but I don't think this is intended behavior as I can't reproduce it on other browsers besides FireFox.

Since the most recent update installed on Firefox, my homepage no longer loads on opening the browser. Instead, a blank page loads, and I have to hit the home button in order to get to my home page. I've checked and none of my settings have changed, so don't see what else it can be other than some kind of bug?

Issue: Rapidly scrolling up or down often creates an unintended blank space (margin) at the top or bottom of the tab list.

Symptom: When this gap appears, the mouse cursor's focus becomes misaligned with the actual tab selection point by the height of that gap.

Behavior: Scrolling back toward the gap usually forces it to disappear, which also restores the correct alignment between the cursor and the selection point.

Reproducibility: The exact trigger is inconsistent. While it happens most often during fast scrolling, it sometimes occurs during slow scrolls as well. The frequency is unpredictable—sometimes occurring every time, and other times once in five attempts.

I get scam messages that say "Trojan virus detected!" on Mozilla Firefox which I cannot delete. I have run antivirus scans which show there is no virus or malware. I have shut down the desk top. How can I go to reinstall Mozilla Firefox default settings or do you have another solution?

Okay. So I downloaded Firefox on my chromebook from flathub, but it keeps crashing. I open a new tab: it crashes. I close a tab: it crashes. I don't open or close anything: it crashes. I don't touch anything: it crashes.

I've says that either my theme or one of my add-ons is causing the crashes but I removed my theme and it still crashes and I can't remove any add-on because it crashes if I try to open a new tab.

Now, did/does anyone else have this problem or am I just stupid and missing a very obvious thing.

how do i delete or remove the message about could connect error
