I'm running the latest version of Firefox (80.0.1) on Windows 10 on a new computer with a fast processor and 8 MB of RAM. Yet browsing is often quite slow -- much slower than on Chrome -- and Task Manager shows that Firefox alone routinely uses 3.5-5 GB of memory. (Even writing this message is frustrating; I have to keep stopping and waiting for it to catch up.) At the moment I have 9 tabs open, most of them sites that don't auto-update. And no video. I find myself closing out of Firefox and restarting it periodically, which helps for awhile but is annoying.

Is it just me or is there a systemic problem here?

I have had to change my email address and have tried to update after I have logged in under my old email account. This request sends a message to my old email account in order to proceed, however I am not able to receive emails on the old account. I have tried to create another account with my new email address however message states I am already signed in. There seems to be no way to sign out. I understand I may receive email responses however I will not be able to access them.

I'm trying to print this page (https://eecaunt.github.io/kanji-sakuin.html), but firefox only prints out the first page, then stops. (Here's a small test version of the same page: https://eecaunt.github.io/kanji-sakuin-small.html)

You can see in the picture that it gets cut off.

Here's the pdf of the picture: https://mega.nz/file/6wwBUIaC#swNET5o7oGArqOuhxLqGhsPKElxznIe2aqvI0TFKO5E

If you see weird overlapping text, then just reload the page. idk why firefox sometimes doesnt finish loading the page…

As an aside: How do I keep the local links (that are in the webpage) in the PDF that Firefox generates?

A folder in Bookmarks disappeared AGAIN! This is ridiculous. Every now and then Firefox loses a Bookmark folder. To make matters worse, I can waste a lot of time trying to find it and get no where. I have better things to do than trying to find lost Bookmark folders! How can I easily find the very important Bookmark folder quickly? Undo does not help.

Hello,

in our company we use firefox esr 78.2 and have blocked the installation of add-ons with our gpo-settings. But we need the openh264-codec-plugin to work (for video conferencing). Is there a chance to only allow / whitelist the openh264-plugin, so firefox can complete this codec-installation ?

We need something like the chrome-policy ExtensionInstallWhitelist: https://www.chromium.org/administrators/policy-list-3#ExtensionInstallWhitelist

thanks in advance and greetings from germany

PayPal pops up a window, which I want to dock as a tab in the main Firefox window.

How do I do that? The "natural" way was to grab the popped-up window and drag it onto the hamburger menu. A quick search only revealed a preference setting to force pop-ups to be tabs, but that is before-the-fact, whereas I would like an after-the-fact solution.

Thanks in advance.
