I-Firefox Community Forum

I'm very frustrated with FF. It's running slow. Downloads are slow etc. I've tried everything that FF has recommended up to and including "refresh" with no effect. It's getting to the point I'm considering not using FF. Does anybody have any suggestions?

Every 1 - 2 hours Firefox stops loading pages and I have to shut it down and restart it and restarting takes around 6 clicks on the icon to get it to start.

Also one time today I lost all my pinned tabs and had to manually restore them one at a time.

Using Ubuntu 24.04.2 and latest Firefox. Cleared cache but doesn't help.

Lately, I’ve noticed Firefox consuming more RAM, especially with multiple tabs open. Is this a common issue in recent updates? What are some tips to optimize Firefox performance on lower-end PCs? Would love to hear your experiences!

Is this a bug or config problem?

Occasionally, FF (Linux desktop) starts using a lot of memory. I kill tabs (sometimes it is OK to kill YouTube or X, sometimes not)

Eventually it starts impacting the system using so much memory. I terminate the FF instance. Often. More often than not. There is a separate task still running and I get the "Firefox is still running" when I try to restart. I then kill the remaining FF task via the OS or the process monitor. Then FF restarts.

Is this an issue with addons (I am running very few - uBlock Orign, and Privacy Badger and Cookie AutoDelete. Are the only ones active most of the time) Or is it an actual bug with garbage collection, and tasks getting away? Or is it an OS issue?

Was prompted for various system updates including apps(Firefox). Performance has been very sluggish. At some points, it feels like I'm browsing on dialup. I have a 1GB connection from my ISP.

Not sure if this is a Firefox issue or in conjunction with the other system updates.

For about the last month, if I click on a link in an email or on a website that should connect to another website, there's a long delay in reaching that second site. This did not happen before. The delays are intolerable and do not occur on Chrome, for example. I prefer to use Firefox, but I feel I have no choice but to use Chrome instead. Can my issue with Firefox be fixed? Thank you for considering this issue.

For the past few weeks Firefox has been crashing and freezing often. Crashes are worst when trying to access Protonmail, which almost always crashes the tab instantly. Freezes happen most often when browsing Reddit, and also when watching Youtube, but crashes and freezes can happen on almost any website.

I have tried changing profiles, refreshing and uninstalling/reinstalling, but the problem persists and seems to be getting worse over time.

Here are some recent crash reports:

Will be grateful if someone can help me get to the bottom of this Thanks

Today Firefox crashed twice and a Tab crashed once! What's going on with Firefox? It's especially disurbing to have it crash during a long video and then you have to find where you left off.

Firefox Nightly (next generation web browser test) has no animation delay when playing sprunki, but there is a bug in the beta and current versions that become delay. (That's why I use other browsers.) There is no delay in other browsers. I hope it will be fixed.

I restarted Firefox on my Mac earlier, which I think updated it from 136 to 137. After reopening it, web pages won’t load anymore. They either time out or just load indefinitely without doing anything. I went through the troubleshooting page and tried reinstalling it, which didn’t help. My computer’s firewall is off as well. I’ve tried refreshing it multiple times, and I get a message that Firefox has crashed before it actually refreshes. After that, pages will load normally for a very short amount of time (about 30 seconds) before stopping again. Pages are still loading normally on Chrome and Safari, so it’s only Firefox that’s having an issue. Does anyone have any solutions for what this could be/ways to fix it?

I have observed that firefox has a coloring problem. When firefox is minimized to the toolbar, after a while, maybe a few minutes, when it is opened, there is always black uncolored content at the bottom of the screen, occupying about 1/3 of the height.

Attached are two screenshots.

I recently updated my Firefox browser from version 136. to version 137. and after the update I was unable to get online to any website I tried and Firefox would freeze and crash, generating a crash report that Mozilla probably didn't get because firefox couldn't send it. Safari was working, as was Chrome, so I know it wasn't a network issue. I cleared the cache and tried again and still nothing. I then uninstalled Firefox and reinstalled it from the Mozilla website, (had to use Safarii to get the Mozilla website) and still could not get to any websites. I'm on a Mac runnning OS 15.3.2 and I have a bootable backup of my machine that still had a copy of Firefox v 136 which i reinstalled on my mac and it works. What can I do to update to 137?

From the last two Firefox updates, I no longer can move sites screens around on my Mac Air laptop. Only one page at a time shows up and consumes the screen. I am no longer able to copy and past and move info to another screen. A couple of weeks agom I cleared my cache but not sure that had anything to do with it. Please suggest solutions. Is there an add on or something that needs adjusting?

Thank you.

Hi Team,

When we enable Netskope, all the searches breaks (specifically with Google Search Engine). It takes about 2 to 3 mins to do the first search, after which it continues to work normally.

Furthermore, facebook takes too long to load (~4mins).

The netskope support team has asked us to make a few changes in about:config: 1. network.http.http3.enabled 2. QUIC protocol 3. network.udp.enabled

None of this works and even if it works, the problem is we have about 1500 devices.

Are there any reported issues ? And is there anything that we are missing ?
