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?

Does anyone know how to add a sidebar with just the icons (i.e. for bookmarks, history, and sync tabs) and only show the full sidebar by clicking the corresponding icon. Can that be done through userChrome?

I have attached two images that illustrate what I'm trying to accomplish.

Preamble: All program updates are accepted when proposed on any of my 2 PCs, Linux or Firefox and other programs.

Situation:

  • Many multiple instances of Firefox are launched but can't be completed on my old (11 years old) tower PC (Linux based),
  • seems to saturate video card with multiple instances of screens (1 or 2 minutes at most) until it prevents other programs (eg Open office) to run
  • Tower PC works well for other programs (open office) if Firefox in not launched
  • while it works well when Firefox and other programs are launched) on my light PC ASUS (also with Linux) 3 years old.

Do I miss required minimal memory size on hard disk or on RAM, or is this an issue on Firefox, or...?

Can anyone please help and advise? Regards

Hello.

I am using Ubuntu 21.04 and after the upgrade I got different issues with Mozilla products. FF is: 88.0 64-bit TB is: 78.8.1 (64-Bit)

One is: "Firefox is already running, but is not responding. To use Firefox, you must first close the existing Firefox process, restart your device, or use a different profile." appears if I click on links in emails. It doesn't matter if they're linked to youtube, are an online version of the email etc. Always the same message.

I tried to assign Firefox as a standard browser and changed to another one, started the system again, ran Thunderbird and Firefox and it still happened. I tried changing something in the config editor, doesn't help at all. I checked for files / attachments and what should happen with http/https. There's no entry, which is fine according to mozilla help. The settings are the same as before the upgrade. I don't understand why it doesn't work anymore.

And second problem is: When clicking a email link in Firefox it doesn't open in Thunderbird. Error message is: "Thunderbird is already running, but is not responding. To use Thunderbird, you must first close the existing Thunderbird process, restart your device, or use a different profile."

It also doesn't work if I have run FF and TB in safe mode at the same time or in other constellations (FF in safe mode, TB not and vice versa)

Any other ideas?

I have Firefox installed on an XUbuntu 20.04.2 LTS machine. preferences to "restore previous session" on startup. Intermittently, when I launch the browser, one of my windows has a very strange appearance (please note the general look of the window in the attached screenshot and ignore the "page cannot be displayed" message, as the screenshot was taken when I was not connected to the Internet.)

I have already tried reseting Firefox and that does not make the problem go away permanently; it always comes back eventually. (Note: I cleared cache before, and cookies after, taking the screenshot but before opening this support request. So the "troubleshooting information" attached reflects how it is after cookies are cleared.)

Sorry if this has been said, i haven't been able to find it using the words i know. First of all, i'm newbie in general so if anything is missing in the explanation just let me know. My computer uses Linux ( Ubuntu 17.10).

The problems are several and are connected, i believe. Some years ago, when updating the firefox browser throught the "official app store", the name of which i only know in catalan, "programari" and haven't been able to find the analogous name right now. The update was actually an installation of firefox quantum that duplicated my Firefox browsers ( at least in icons, i had both ) as i now had the updated one and the old one, which i simply stopped using. Several problems arose in using this format , for example when i try to open from terminal Jupyter lab i needed to have already open the quantum version, otherwise it would simply open it in the old browser and that was a problem for other things not interesting here maybe. There came a moment where this new so called quantum browser stopped working, i.e. it crashed in completly white screen, while not being able to close it, and, furthermore, without being able to uninstall it, again from this app store, as everytime i tried it the app store window would just show me that it was working ( i pressed uninstall and the "cercle around" dynamic icon showed), but no matter the time i left it to finish it never did/does. Now i'm trying to, again, update the OLD firefox browser i had because it is so old ( version 61 ) that many webs can't even be used ( Netflix for example). HOWEVER, i have to say that any of the official helps to download/update firefox has been of no use for the moment. That is, the "update firefox to latest release"( https://support.mozilla.org/en-US/kb/update-firefox-latest-release) page assumes that the update will take place by just going to << Help->About firefox>>, but it doesn't; and the alternative method, using "Choose which Firefox Browser to download in your language" page ( https://www.mozilla.org/en-GB/firefox/all/#product-desktop-release) downloads me a compressed file ( in concrete firefox-88.0.tar.bz2). What is the problem with this? i haven't found a single word saying what to do after this download... i'm a newbie i only see a whole bunch of archives and files within but i don't have the Icon to press( yes, there is the firefox executable program that if you press appears the browser, but how can i place, and use, this outside the file( when i move it outside it stops working)) and so be able to use access the browser without having to go all into the downloaded file?

I know this is extremely long and i apologize for it. Here in the following i'll simply summarize the questions mentioned in hope that someone has any answer: 1) Why Firefox quantum, installed from the official app store in Linux ( it is/was the only Firefox appearing there as if it was the older version), didn't update the last version i previously had and made instead a duplicated, conflicting sometimes with the older ( Jupyter lab problem mentioned ), version. 2) Why has this Quantum browser suddenly crashed in my computer and why i can't even un-install it. 3) What is to be done with the update-downloading compressed file ( coming from https://www.mozilla.org/en-GB/firefox/all/#product-desktop-release ) as to end up with the nice-looking, usually found, firefox browser icon in the screen, instead of having to go inside the file to use it.

Many thanks to anyone being able to help this troubled-guy in his proces of not going back to google chrome and windows.

if an extension requires an 'Access your data for all websites' permission then firefox requires me to choose either allow this extension to steal all my sensitive data, or not to use the extension at all.

for such cases, chrome allows me to choose when and where i prefer to allow the extension to see these data and when and where to restrict it from accessing them: Site access Allow this extension to read and change all your data on websites you visit:

  • On click
  • On specific sites
  • On all sites

does firefox allow this somehow? i'd prefer to have an option to restrict such access in some cases by clicking the extension button, in some - by white or black listing specific sites (mostly whitelisting), and for some cases - do not restrict.

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.

# 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

Here is my usual 2nd profile in idle mode:

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

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.
