I am using the latest version of Firefox with Mojave on a Mac.

Lately I have experienced slowness despite the fact that I didn't add any software and I have Norton checking for viruses. Recently I got a message "Your system has run out of application memory" when I had 5 tabs open in Firefox. I checked Activity Monitor and it showed Firefox using 1.16 GB. 7 other apps were open, the next one with the highest memory usage was Mail (465 MB). Activity Monitor showed 30 instances of FirefoxCP Isolated Web Content entries.

I attached a screen capture showing what Firefox was using in one of these instances. Is this "normal" with 5 tabs open?

I closed the open tabs and quit Firefox. Memory usage by Firefox went down, but after a short time the problem happened again.

A search on the internet showed lots of similar complaints about FirefoxCP Isolated Web Content. Is this a known bug? Any way to avoid this problem?

Thanks.

I cannot access the bill pay in my bank account.

Why can't I access Bill Pay? How do I unblock without allowing access to unwanted ...?

I have to buy a new iMac, which now comes with Sonoma. Is there a version of Firefox that works without major issues on an iMac with Sonoma or is it better to wait? Thanks.

Firefox "Window" drop-down menu is missing open windows. This has happened for a few upgrades. If I add a new blank window, the drop-down menu will fully populate, though if I navigate to any of the other pages, it goes back to being incomplete.

Each attempt to log in to my bank account, using Firefox browser straight up, results in an access denied refusal. If I go to Duckduckgo.com and search for my bank, I can access the bank account. I wonder if you have other complaints/comments to that effect, too. It is an aggravation and my bank, Navy Federal Credit Union (NFCU), did not have a solution but suggested I contact Firefox direct.

Here is a copied response, as an example:

"Access Denied

You don't have permission to access "http://signon.navyfederal.org/siteminderagent/forms/nfcu.fcc" on this server.

Hello Team,

Firefox does not play well with how you customize keyboard shortcuts on Mac i.e. Go to System Preferences > Keyboard > Keyboard Shortcuts.

By default - Move Cursor to Address Bar - Cmd+L Bookmark this Page - Cmd+D

I would like to switch these two shortcuts but there does not seem to be any way. Please help me out.

Thanks, Naman

OS: Mac OS 10.14.5 Firefox Version: 113.0.2

Settings gives me multiple options for handling a .pdf file. The first three are (1) Open in Firefox; (2) Always ask; and (3) Save File.

If I select "Open in Firefox," the file will open in my existing window. If I select "Save File," the file downloads to my desktop.

The problem arises when I select "Always ask." If I then select "Open in Firefox," the file opens (in a new tab!) and simultaneously downloads to my desktop!

Is this a system glitch, or am I somehow doing something wrong?

I am trying to print specs for a computer (beck & front) at:

https://www.dell.com/support/manuals/en-us/xps-8960-desktop/xps-8960-setup-and-specifications/back?guid=guid-f2dda353-ba5a-44c0-b85f-6bf1b8c70d15&lang=en-us

The print-out with Firefox captures only half on the picture and relevant info. Luckily, Safari prints correctly. I am wondering why can't Firefox do the job so I do not have to go to Safari for printing? This issue is not specific to this website, it happens often in many other cases. Is this being worked on? Thanks.

At some point, I've noticed that certain behaviours expected to occur when pressing the Escape key no longer did. Those behaviours mainly involved triggering some Javascript, including functionality in keyboard-related extensions, such as Tridactyl. Browser-level functionality on the other hand, such as pressing Shift-Escape to open `about:processes`, or pressing Escape to close Search Suggestions when the URL input bar, continue to work as before.

Upon investigation, I found it is specifically the javascript Keydown event that isn't being registered, while the subsequent Keyup event still is. I used https://w3c.github.io/uievents/tools/key-event-viewer.html to test this.

I also found that starting Firefox in Troubleshoot Mode (Safe mode) doesn't resolve the issue. On the other hand, creating a new profile does.

I've looked at the modified settings in `about:config`; there's a lot, but nothing stands out as being related to keyboard input or javascript.

Can someone please help me find what is causing this?

Where did all my saved logins and passwords go? Why did Firefox delete all that information? And NO, using about:profiles to check for alternative profiles, etc., does not work! There is NOTHING there! VERY DISAPPOINTED!!! This is going to cost me hours/days to fix, unless I can find out what happened and get all that info back!

I searched in Google and this website for instructions for how to delete specific cookies for a website. Many instructions are probably for older versions of Firefox.

I used to be able to login as of this morning to Wizzair.com. Then suddenly, regardless what I do, I can no longer use Firefox to login. I used the Preferences/Privacy & Security/Cookies & Site data/Manage Data for Wizzair.com to remove the cookies for the website, but it didn't help. I changed the password, it didn't help.

Their chat support sent me to their Privacy statement. There, there is custom list of cookies that they use. I was told to try to delete them individually... I have no idea how to do that and I could not find a method that works.

I can login the website using Safari. Any suggestions for what to do to be able to use again Firefox to login into this website? Thanks in advance.

Counter code numbers do not show for me here with FF but do show for Safari (which I don't like): http://robfalcone.com/rf/

Hi there,

I've got plenty of bookmarks organized in folders and sub-folders (never could wrap my head around using tags). Normally, hovering on top of a folder or sub-folder just opens it. However for some unknown reason, some folders just don't open on hovering. By contrast, opening the "Manage bookmarks" pane shows all bookmarks are there and functional. The issue only appears in the menus, and I'm not sure when it appeared exactly.

Already tried: Renaming faulty folders: no effect Moving bookmarks into a newly created folder: no effect Moving faulty folders into an already-working folder: works, except if the folder is the one containing the root menu.

Screenshots: A working sub-menu: https://user-media-prod-cdn.itsre-sumo.mozilla.net/uploads/images/2022-08-01-10-56-24-be01e3.png

How to solve this strange issue?

Is there a way for the new window animation in Firefox for Mac to be disabled?

Safari does not do this, but firefox has a... ~100ms animation for new windows that's extremely frustrating for those of us who do not use tabs (Apple's Exposé/Mission Control obsoletes them).

I haven't found a configuration in about:config, although I've been able to disable a few others.

After updating FF to 115.1.0esr (MAC) I cannot get the Walmart website to work. The home page comes up but it immediately goes to the account log in page [ sign in or create your account ] ( https://www.walmart.com/account/login?vid=oaoh&tid=0&returnUrl=%2F ). I have deleted all FF cookies etc.

It has been doing this for several days, since the update.

NOTE: Walmart website works normally on Safari and Chrome. Thank you, Mike

Hi, I just discovered something odd. Trying to troubleshoot something with an android app communicating via web and laptop to free up the phone, and the relevant website has a chat popup and Firefox won't open the popup. I added the website to the whitelist and saved, but still wouldn't. Tried troubleshooting mode, but nothing. Switched to Chrome and it works fine. Cleared cookies and cache and restarted Firefox, but still no luck. The website is ExpressVPN.com. Macbook Pro OS10.14, Firefox up to date, version 115.1.0esr (64-bit).

Is there a way to disable the keyboard shortcut Command-Shift-Delete on MacBook so it doesn't open the clear cache dialogue box? I use this keyboard shortcut all the time to empty my trash; I've occasionally accidentally triggered it in Firefox when I was really just trying to empty my trash.
