After migrating from Firefox 87 to 88.0.1 under linux-64 (debian 10), the browser became very slow. Typing has a delay of 2-3 seconds between end of type and appearence on screen. Same for loading pages. Migrating back to firefox 87 is a nuisance since part of the setup is lost and mozilla keeps insisting daily to switch to firefox 88. The articles in "Fix slowness" do not seem to help.

Any suggestion?

Recently (a few days), I have noticed that math formulas are displayed as plain Latex code in a Moodle-based course viewed on my windows Firefox browser. There is no problem with other browsers and android devices. It seems to be related to the automatic update to the version 88 of the Firefox browser. Is any one else facing this problem? Does anybody know a solution?

I use Firefox on Ubuntu 21.04 LTS and recently started facing delay of 3-4 seconds while trying to open any add-ons in top bar or even when trying to navigate application menu. I recently moved from windows to Ubuntu, no such lag or delay was there in windows.

What I tried- I tried to troubleshoot this problem with the help of troubleshooter present in Firefox and used the 'Refresh Firefox' option but still it was lagging too much. I also tried to remove all add-ons but still it was of no use. My system is fast enough to handle Firefox.

After installed some expired certs on a server in house, I try and bring up a management page that worked fine prior. The error is: The server presented a certificate that contains an invalid encoding of an integer. Common causes include negative serial numbers, negative RSA moduli, and encodings that are longer than necessary.

Error code: MOZILLA_PKIX_ERROR_INVALID_INTEGER_ENCODING

How can this be worked around, a setting of some sort maybe?

Thanks for any input

# Ubuntu garbage data increases exponentially
## Intro and context

Hello. I am a power user that works in software and web development. I have been using Firefox on and on for most my life, but full time as my main browser since late 2018. One thing I love Firefox for is its lightness on memory compared to that of Google Chrome, and also its open web standards, open source, privacy, ethical owners, and customizations. I have been using Windows 10 up until July 9th 2020 before I switched to my first main Linux desktop. I have always kept my eye on CPU and RAM usage, as high CPU drains battery and running out of RAM results in a system crash. I actively keep many tabs open (less than 100 but more than 60) I ensure that they are light. I mostly have GitHub tabs open, but I keep a few other things open as well, mostly Wikipedia/wiktionary and duckduckgo tabs, a pcloud (file service) tab, but sometimes a youtube tab or two (rarely a reddit tab)

## Issue

I have been noting that garbage collection is getting exponentially worse over time. When I got my laptop, I was able to keep 2-3 fully packed profiles open at all times, and never having to close Firefox until shutdown (after about 12-16 hours uptime) I rely heavily on Firefox profiles for organization. It has been getting exponentially worse. Starting in late 2020, I had to reduce the max number of open profiles to 2, and in 2021. In early January, I had to start closing the profiles once a day to free up 2-3+ GiB of RAM (swap doesn't change much, that is the garbage data that isn't being cleared, it normally ends up at 800 MiB to 1.7 GiB by the end of the day) and now (as of January 22nd 2021) I have to close Firefox 2-3 times a day to prevent my system from getting overloaded, as Firefox eats through 1-2 gigabytes of RAM per hour, even when idle. I have noticed several processes titled `web content` that use 200-600 MiB each (there is usually 2-7 of them) I am wondering what I can do for Firefox to prevent high RAM usage. For reference, here is my main profile in idle mode:

Mozilla is refusing to let me upload images right now, so I will link them

https://github.com/seanpm2001/seanpm2001/blob/master/FFTechSupport/Jan22/MProfile1_Idle_1.22.2021.png

Here is my usual 2nd profile in idle mode:

https://github.com/seanpm2001/seanpm2001/blob/master/FFTechSupport/Jan22/MProfile2_Idle_1.22.2021.png

Here is the RAM and SWAP usage before my 2nd refresh today (uptime: 8 hours 46 minutes)

https://github.com/seanpm2001/seanpm2001/blob/master/FFTechSupport/Jan22/FF_GF_Open_1.22.2021.png

And here it is with Firefox and Nautilus closed (I forgot about nautilus before getting the first 2 pics, it uses a lot of memory depending on its usage):

I have lately suspected that GitHub may have gotten heavier, or is sending too much data via AJAX methods, but I am not entirely sure.

    1. System specs

Device: `Dell XPS 13 9XXX`

Operating system: `Ubuntu 20.04 (Focal Fossa)`

Linux Kernel version: `5.4.0-48-generic`

Processor type: `Intel Core i5 10th generation`

Processor specs: `Intel® Core™ i5-1035G1 CPU @ 1.00GHz × 8`

Processor mode: `x64`

Desktop environment: `GNOME 3.36.1`

Windowing system: `X Desktop environment 11`

Memory: `7.4 GiB (8 GB)`

SWAP file: `2.0 GiB`

Firefox version: `84.0.1` - I haven't updated in a while due to fear of memory increase and instability

Number of Firefox profiles: `61` - no new profiles created since December 26th 2020

I am wondering what I should do about this. I work with hundreds of projects, so I can't close too many tabs, as it becomes hard to access and manage. I intend to close 16 tabs in the next month, as I am freeing up some projects.

Hello,

I've been getting an error for some time now. Firefox tabs suddenly crash (usually media tabs with video, like Twitch or video conference sites) and I can't seem to find a solution. But most importantly, many videos or live streams show graphic artifacts. You can check it in the attached screenshot). I have tried many things to solve it, but none worked. This is what I tried:

  • Changing cables and monitors.
  • Disabling extensions and plugins.
  • Disabling hardware acceleration.
  • Installing Firefox from scratch.
  • Installing an old version.
  • Installing Nightly.
  • Removing the GPU. The issue persisted with a different video card and with integrated graphics. So the GPU is not the issue.
  • Trying using another OS. I thought my Windows install might have been corrupt, but it also happened in Ubuntu.
  • Trying other browsers. I tried Chrome (which resulted in the issue as well) and Edge (which surprisingly did fine, it's my only solution right now).

I would love to keep using Firefox but it's a pain to watch media like this. I don't know if the issue might be from the motherboard or another component. Between the crashes and this I can't use it normally.

I can try providing any details needed to solve the problem. Could you please help me? I don't know what else I can try.

Hi!

Been test driving Proton and quite liking it, but on both FF 89 and 90 im running into issue where opening bookmarks or history via library menu freezes browser ui. Restoring and maximizing window restores the functionality again until next time i try to access said menus. After restoring and maximizing it seems like all the actions i've tried happen at once. See video https://imgur.com/a/8f2tl0l. I have roughly 100 bookmarks, so that shouldn't be an issue.

This happens also on completely fresh install without any backups and new profile. As soon as I import my bookmarks or even bookmark couple new, random sites without restoring old bookmarks, this problem begins manifesting itself.

I've tried troubleshooting mode and that helps, but im still sure what causes the issue as just disabling hardware acceleration does not help and I have no other themes or extensions active atm. Just in case I've also tried updating graphics drivers to no avail.

Stable FF does not display such issue.

I recently was looking through my autofill addresses when I noticed a name that should not be there. Someone I do not know in some state that I do not live in. I quickly changed my firefox password and various passwords that may have been compromised.

My question is, how worried should I be? How did they get my password or access to a PC with my account active on it. Then why would they be so daft to save their name and address as the autofill?

Is there any way I can check when it was made or pass this on to Mozilla support?

Hi, It appears my firefox account was comprimised, and they where able to gain access to all stored info and saved logins casuing major damage.

All accounts have since been secured, and in process of recovery from effected sites.

With the browsing history logs, it looks like it has tabs for the date it was added and when it was last modified, but not actively used, are these meant to be by default?

It would also be a nice feature to see which device was used to access the webpage, as i have had to wipe 2 computers as a precaution in case the either was hacked into, if i could of seen which one, this might of been preventable

If it could say for example Site Device Added YouTube My Device 1 12-05-2021 Gmail My Device 2 11-05-2021 Amazon unknown device 11-05-2021

Action can be taken sooner

Looks like feedback site is undergoing changes, so i can't suggest there.

Cups appears to produce expected files in the spool directory; the printer wakes up, but goes back to sleep after a normal timeout. Printing the same page with "Print using system dialog" works perfectly.

I have been using Firefox as my browser for years to open my QVC account. Last night, while looking at my QVC account I tried backing out of the page I was on and I could no longer get back into my account. I tried using another computer and it worked fine. I also tried switching to Safari and again I could log into my account. I am using a MacBook Pro. I tried to refresh Firefox but that didn't work.

I can see the main QVC webpage but have no way to access my account or even open QVC. Firefox is working for everything else that I access.
