Firefox Support Forum

Dear Mozilla

Long time user (love it) but the browser is consuming a lot of memory. With the same windows open in Chrome, Firefox is consuming 5 times the amount making the system slower glitchy.

This has been an issue for awhile and I checked all the posted solutions. Either the software is consuming an that is normal or something is running in the background. Firefox is at 1831.5 MB as I type this.

Can I uninstall then reinstall? or is everything going to return?

Thank you in advance

Ron

Further to my request this week, where Ididn't reach the right forum.

Greetings, for some reason lately over the last couple weeks I have noticed that when I open a link to a site that I've had in my bookmarks for years it now opens that link or that page and then within a couple seconds another tab will open for advertisement or possibly even the duplication of the originally called upon link in the previous tab. I would like to stop these additional tabs from opening automatically without my request.

thanks in advance,

This is the link that Fox was reporting difficulties playing on a Mac running Firefox. I just ran it on my ancient imac using an older LTS version of firefox and am not having any problems (nor with chrome)- 

https://hlsjs.video-dev.org/demo/?src=https%3A%2F%2Fgyllp63pcjwbfl.data.mediastore.us-[…]mZhbHNlLCJsZXZlbENhcHBpbmciOi0xLCJsaW1pdE1ldHJpY3MiOi0xfQ==

I made a mistake and installed Firefox in the wrong location. I uninstalled and attempted to reinstall where I wanted the software to be.

The installer now tells me that I had Firefox before and will only reinstall it in the previous directory. No other option is offered.

I am LONG used to being deprived of user choice by the likes of Microsoft or Apple, but Mozilla SHOULD KNOW BETTER.

Can you help?

Thank you.

I want extensions to have white/black-lists, so they're only allowed or blocked on certain pages e.g facebook container ruins instagram experience... and I can't block it on *instagram.com* Such feature would significantly enhance UX on firefox

Thanks, Rob.

Hello, I did something stupid. I was trying to set up the dark/light theme via cli, and I asked openai about it.

It suggested this command:

echo 'user_pref("lightweightThemes.selectedThemeID", "firefox-compact-light@mozilla.org");' | jq -s '.[0]' > ~/.mozilla/firefox/*.default-release/prefs.js

Which resulted in the following error:

jq: parse error: Invalid numeric literal at line 1, column 11

When I opened mozilla, my profile was reset, and websites won't load (except this one!). They just hang there loading forever. My internet is fine, chromium works perfectly.

So how do I fix this and is there a way I can recover my profile? (Yes I know I should've made backups)

Using Nord Pass extension on Mozilla fine until today, when clicking on the green icon for stored username and password, this appears - "sudden error message : can't handle ITEM/URL_SEARCH type message"

YOU KNOW I HAVE OTHER PROGRAMS TO RUN AND FIREFOX HAS BECOME SO BLOATED THAT IT EATS UP ALL MY RAM FURTHER MORE I PURCHASED FIRESHOT AND I CAN'T RUN IT BECAUSE YOU DON'T WANT TO LET ANYONE RUN AN ADD ON. THIS BUSINESS OF UPDATE AND BING HERE IS ANOTHER UPDATE AND CONSTANTLY BEING PLAGUED TO UPDATE FIREFOX. YOU COULD PUT ALL YOUR UPDATE IN ONE UPDATE. YOU COULD SPEND A LITTLE TIME AND TAKE THE BLOAT OUT OF FIREFOX. IT DOES NOT HAVE TO SO BIG. IT DOES NOT NEED TO COVET ALL THE RAM.

Dear Firefox Community,

my ff browser won't open the following websites:

https://www.haaretz.com/ (here it says: Error 54113) and https://archive.ph/ (this won't open at all without any notification)

Could you please let me know how get them to open?

Thank you!

Wanted to export some bookmarks, and couldn't figure out why (latest Firefox) Bookmarks "Library" was missing relevant buttons/menus. (Screenshots attached.)

After testing, found they actually are there, but have have almost no contrast vs background - that is when "Manage Bookmarks" is called from a Private window. But things look fine when called from a Standard window. (No extensions; same in Safe Mode.)

Can anyone advise?

A simple workaround is to bring a standard window to the front first, but am curious if this is Firefox on all systems? Only FF Linux? Only the particular (default) settings of my Linux Mint 20.3 Cinnamon installation, and display? Not even sure a Bookmark management window is ever meant to assume the theme of the foreground window (here Private browsing's dark).

Thank you.

Since the last update (earlier this week) firefox uses large amounts of memory. It shows in the windows task manager 20 and more instances of firefox being open and one of them using 85%-90% of the available memory. I looked up help articles regarding this issue and one of them mentioned to "Delete content-prefs.sqlite file". When I do that it will help for a short period of time but then the issue is happening again. I'm using Windows 11 64 bit.

I'd appreciate some advice on how to deal with this.

Archived 2020 query at https://support.mozilla.org/en-US/questions/1360922#answer-1465978 asked for time-stamped history list. Instructions in the response say after CMD(on Mac)/Shift/H you will see names of columns above the list. This does not appear - possibly deleted since the answer.

I'm trying to argue with a bank that I made a payment in business hours, and a time stamp on my history record would bolster my argument.

Is the list of columns mentioned available somehow? Can a date/time stamp be added to every history record? (Date is known, but not shown as a date stamp.) Is this info in there, but hidden, and available somehow?

4 PM, November 7, 2023 EST. The "About" page of all YouTube channels suddenly disappeared, whatever the the login status. A compressed version will show up from a channel's home page when clicking on the site description from its Home page. Make things weirder, ~6:15 PM it WAS visible from the Tor browser but started acting the same. I have no ad blockers, or ANY extension installed on any apps, including Firefox/TOR browsers. Updates to both browsers were made prior to this behavior. It may be Google/YouTube's fault but it's becoming frustrating because I prefer Mozilla's browsers over Edge or Chrome.

Hi y'all! I've been trying to get netflix to play recently, and I keep getting the error code F7351. I tried looking it up, and didn't get anything, and also tried to dis- and re- enable DRM content, and that didn't work. Does anyone know what to do? Thanks for any help!!

I moved to Firefox because I have autism and someone told me it would help block the popups and moving content that makes using the web exhausting and difficult. And it does!

The trouble is, it replaces them with something worse – a grey screen that rolls continuously from left to right. It's impossible to focus on text with such intrusive visual distraction, so I have to shut the page down. It seems to occur on so many websites that at the moment it's not worth trying to use the browser.

Half the problem is that I don't know the right term to describe it, which makes troubleshooting a bit complicated. Hopefully someone will recognise it from the description, though – if so, is there any way of stop it moving, please?

Thank you!
