Firefox consumes almost 2Gb of RAM with only one tab open. I find this surprising, and it's a major performance issue for me.

Do you have an explanation or solutions to reduce this memory overconsumption?

I have updated the Firefox to 133.0 (Build #2016056951), hg-24fce2fbde95+GV: 133.0-20241118181856n AS: 133.0. When I open new tab, and open any website, the default is set to "Desktop Mode", how do I reset it to normal default mode?

Hello everyone,

I have a problem. I have seen that there have been discussions about this in the past. Unfortunately I have not found a solution and the discussions are all archived.

Now to the problem: Various pages have no favicon in Firefox when I drag them into the bookmark bar as a bookmark. However, when the page is active in the tab, a favicon is visible there.

The problem does not seem to be unique to me. Several people have tested it. It also seems to be a problem in Firefox only. In other browsers, this problem does not occur.

What can website owners do to fix this problem?

Here is an example of a site where I have the problem. www.organspende-register.de

Many thanks in advance. Best regards

Firefox beta usually works OK but random webpages either take ages to load or even hang indefinitely. Most of the responses I've seen on this subject simply ask for more info re websites, extensions etc but other browsers don't have these problems, so it looks like a core Firefox thing.

When you have the 'Open links in apps' setting turned on, clicking a link will open the app but also open the link in browser as well. This is annoying because if I'm searching for something and switching back to the browser, I have to click back every time to go back to the search results.

- This is a problem on Firefox Beta for Android - I have a Pixel 8a - It works fine on standard Firefox for Android - It is not specific to one app - The open in app part works fine. It's just the browser shouldn't also go to the website at the same time.

Hi y'all, when I use firefox DE, there is a bug in which the search bar overlaps with the tabs, after the new release. Is this because I use a custom CSS that reverts the tabs back to the old style? I would really appreciate it if I could still use the old firefox tab style without having my search bar overlapping with the tabs

I was working with responsive view mode and noticed that sensor scroll with mouse is broken. I checked on another PC and the problem there too. I don't know how to describe it, but I made a video and uploaded it to a website so you can watch it.

Hi, w11p laptop. Dev build 133b2 & older (dev builds all).

https://united4respect.app.scaletowin.com/?inviteEmail=psldda%40gmail.com&loginImmediately=true&inviteHasAccount=true

This issue is not just for united4respect. I've encountered it in DNC phone banking login as well, it does seem to be a scale to win set of pages.

Issue: in order to log in to scale to win web pages, it requires me to type in my email address in the provided field in the link above. What I get: nothing. Typing does not happen What I did not do: go into troubleshoot mode What I want: is this an extension issue? Is it a FF Dev build issue? I don't have stable FF here. It's iffy troubleshoot mode fixes, depends on problem. What I did: use chrome. It worked. I prefer FF.

Later: I checked the 2 extensions that could possible be at fault, and they are NOT it: malwarebytes and ghostery extensions. I disabled both. I tried typing in the scale to win website, regular FF mode (not troubleshooting). Still no typing allowed.

I then changed fonts from arial to times new roman. No difference, no typing takes place.

Advise, please. Thank you.

Whenever I try to download a pdf file, I can’t view it afterwards or export it to another app. Also exporting to another app like Goodnotes doesn’t work. Please fix this bug on ios!

Hello,

I am using Firefox app on my android, I have 2 Gmail accounts that I use frequently in this app. Every 10 days Firefox keeps logging me out of my accounts without any notice. How can I solve this issue?

Thank you Ruba

New addons on Firefox become blank on restarting the browser.

They return when I manually disable and enable them once.

How to fix this? Doesn't happen to older addons.

my Facebook uninstall activity disability. and I have lost my Facebook to vector authentication QR code. please open my Facebook account. I am send my government ID.

It's a bit weird, I got the thing you get when you migrate to a new browser - asking if you'd like to migrate history and bookmarks. I closed it because I've used Firefox for years.

When Firefox opened proper, I got a tab asking to restore the previous session, along with a "Welcome to Firefox" tab. As well I got a few popups for other things, basically just stuff you see when you open Firefox for the first time. A couple of extensions opened up a landing page that should only open when you first install them.

All my bookmarks and browser history is there. The settings have all been reset to default. The extensions are there but all of their storage seems to be gone, like my dark reader extension no longer has the exception sites on it. Ublock has the ad count reset and most importantly all my custom rules are gone! I have spent years making hundreds of custom rules, and quite a few took hours to get right. I am sad about losing that.

Does anyone know what might have happened?

When I was looking at my about:config to see I saw these things in the modified settings.

there's quite a few settings here and IDK which are relevant. The ones in the pictures where just the first couple and I show them because they seem to have something to do with this situation "auto migrated" - when it seems like the browser did this because it thinks it migrated, the first screen I got was asking if I'd like to transfer my bookmarks and history (and good thing I closed it,or it might have deleted those too).

After a recent update, I noticed that my toolbar changed suddenly. I was able to rebuild it how I like and most of it stays, however, the "Open A New Tab" button refuses to stay where I want it.

Whenever I open a new window of Firefox, the "Open A New Tab" button is found on the leftmost side of my screen beside the new tabs. If I go to the "Customize Toolbar" page, I am able to move it so it stays to the right of the rightmost tab, which is where I want it to be.

Anytime I open a new window, whether it's through dragging a tab onto another monitor, or opening Firefox the first time after turning on my computer, my change gets reversed.

How can I permanently move this button to the desired position?

This did not become an issue until an update about a week or so ago.
