Firefox Support Forum

I am experiencing many times that Firefox prints garbage, not what's on the screen. To get around the problem I switch to Safari.

Is anyone aware of this or I am the only one experiencing it? Is this a known bug?

One example:

https://www.amazon.com/Delta-Faucet-U6300-Handshower-Mount/dp/B0064TYA4S/ref=sr_1_5?keywords=grab+bar+shower+holder&qid=1655171785&sr=8-5

Prints little circles...

If I switch to Safari, I get on paper what I see on the screen.

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.

When I use Firefox on my Mac, no matter what I have tried it keeps defaulting to the dreaded Bing Search Engine. I understand it has to do with Microsoft, but I don't use any of their products because I don't like them. In settings/search I can restore the default search engines & delete Bing, but it always reverts back to insisting on using Bing again. I have followed several threads about this issue without permanent resolution. Help??

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.

I learned the hard way about a month ago that my main bank will not work with firefox. I've now received notices from two other banks that state they only support safari on Mac. I have run into issues with some others that will either give errors but still allow me to pass through or others that state I have an unsupported browser but still allow me to log into the site - for now.

With this wide a net, this seems to be specific to the security issues in the Mac browser. Is this already being looked into? Is this specific to the new OS and firefox integration?

While I basically trust Safari, I certainly don't want to use it unless I have to and I generally use firefox exclusively on all my Macs and PCs. Can someone shine a light on this? Is there an upgrade or update planned?

Thanks

Greetings... I would like to increase the font size in right click menu box in FF 89.0 (64-bit) (see attached png)

I found a similar 2018 query here at: https://support.mozilla.org/en-US/questions/1241117#answer-1174375

and based on that exchange I added the following to userChrome.css file

/* FONT SIZE IN RIGHT CLICK MENU BOXES 5/1/22 */

1. mainPopupSet menuitem,
2. mainPopupSet menu { font-size: 16pt !important; }

/* */

I closed and reopened FF. This change has no effect on the menu font no matter what font-size value I enter. Have I done something wrong?

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

Hi:

I tried to set cookie preferences for different websites. For reasons that I do not understand, I cannot move the "slider". I even turned of the existing protection for the websites, but nothing changed. I tried the same with Safari using the same computer and mouse, and I had no problems.

Is this a known bug?

I attached a screen capture. Thanks.

Something changed a couple months ago where Firefox's spell check began only catching about half of my typos. Over the last 15 years I have become used to my browser providing spell checking services, looking for the little red lines to point out my mistakes, so now that this feature has stopped working reliably I am constantly submitting items with embarrassing typos, having to go back and edit almost every single post I make after the fact. Is there any way to get this working properly again? Thanks.

I've started getting this error message on certain websites (always the same ones):

The page isn’t redirecting properly

An error occurred during a connection to www.manek.org.uk.

   This problem can sometimes be caused by disabling or refusing to accept cookies.

The same websites still work fine on Firefox mobile, so it's nothing inherent in the sites themselves.

I have only noticed this in the last few days. I had just updated Firefox to version 109 – but it's not specific to one version of Firefox either, as I tried on one of my Macs which hadn't updated yet and is still on version 107, and the issue was replicated exactly the same.

I have tried clearing the cache, restarting Firefox, etc.

Can anyone help me resolve this? Some of these are websites I use quite a lot for my work, and it's frustrating to have to do anything just on my phone.

Someone else asked the same question a while back but the answer doesn't work for me.

The previous answer: 1. Make sure you have "Ask to save logins and passwords for websites" checked in your browser. To check that, Open Menu->Options->Privacy & Security->Forms & Passwords 2. If the above check box is checked, then whenever you enter username & password in any website Firefox will ask you to save username & password 3. Click on Don't Save. So Firefox will save the user name in form data. 4. When next time you open that website and click on user name it will show you the list of entries(If you used multiple use names on same site else will show only one user name) available for that filed.

I get no list of user names.

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.

How to solve this strange issue?

I'd appreciate easy to follow steps (for the last version of Firefox for a Mac using Mojave) to locate cookies for only ONE SPECIFIC website and delete them.

Thanks.

I'm on Windows 10 Auto updated to 108.0.1

UI is broken. See image.

Works in safe mode though.

How to fix?

Or at least guide me on how to backup all my config and create a new profile. Thanks.

I just updated the browser. Just prior to doing that, I used used this website https://www.carpetmdinfo.com/ without any problems. Now, as click on the different tabs of this website (Home, About Us, Our Cleaning Process, etc.), nothing happens. The same website works without problems with Safari.

Does anyone else experience similar problems?

I looked at reporting the problem as a bug, but I am sorry, it is too complicated for me. If someone could replicate the problem and report it, if in fact the same happens to others, I'd appreciate it.

Hi everyone,

I have the problem in the Subject line. FF sucks about 500 MB to be run, on top of which it takes 500 MB per tab, and that makes it impossible to run a research on my 8 GB Mac. Yesterday I was looking for a lamp and had no more than 7 tabs open, 3 of which were largely text, 2 were online shops, and 1-2 were websites with pictures. No Facebook or social media, no YouTube. FF froze, made the whole Mac freeze (well, Mac is garbage nowadays but let's leave that out of this topic), and I had to wait MINUTES before I could close it, because the computer was nonreactive.

When I check online, I see people being like "why can't it manage more than 50 tabs?". 50?!?! My computer dies with a maximum of 10 when it's only text websites!

So, I guess there's something wrong with this.

- I don't have many extensions (SimilarWeb, VPN, and Flash Player), I always use incognito so I can't use the plugin that allows me to use several accounts at the same time, so I can't see what's messing with my Mac. - The Activity Monitor (pretty much Task Manager on Windows) shows "FirefoxCP Isolated Web Content" for each tab, could that have anything to do with my problem? - CPU usage is very low, some 0.5 to 10% max during heavy use. - I seem to remember I used to have dozens of tabs open in the past, although I can't be sure. Is this a recent problem?

I really hope there's a way to solve this, because now I always fear that opening FF while on a Zoom meeting might freeze the whole thing.

Thanks to anyone who might want to shed some light on this big problem.

Screenshots: RAM and CPU usage with 2 tabs open. Two, taking more than 1 GB of RAM and about 250 threads in total? While using 0.2% of the CPU? I'm lost

After a computer reboot, ALL my bookmarks have disappeared. I'm running Firefox 98.0.2 on Mac 10.14.6 - I've followed all the 'help' advice: I opened firefox profiles, it only shows one. I rebooted Firefox (I was left with bare bones) and still no bookmarks and still only one profile. I've looked in the computer 'library' and I can find nothing compressed (the bookmarkbackups folder has 15 items but all are dated 2022). Can someone please help me retrieve them, I'm in the middle of a project and NEED the bookmarks. Thank you in advance!

Hi there,

I just started a seldom-used FF profile to have it synced (you lose FF sync connection if you don't log in within 2 months, I think…). I set up my account for decent security: 2FA, wrote down the recovery key and recovery codes.

As I changed the password recently (didn't re-generate said recovery strings), I expected the disconnected state, all right. So I proceed on entering my new password, and out of curiosity, decide to make as if I didn't have the 2nd factor on hand

The Firefox Sync dialog page now asks me for a "Recovery code" that's 10 digits long. To my great surprise, none of those I saved when first setting up the account worked! I know I didn't use any of them.

More, the terminology had me confused: when is a recovery key used vs. code? Both files contain "Recovery codes" in their name, besides, a "digit" is: "1 any of the numerals from 0 to 9, especially when forming part of a number." Nowhere in Firefox Sync a string of 10 "digits" generated: the "recovery key" is 32 character long, in 8 sets of 4 characters, and the "recovery codes", as I understood it, 10 "character" long (and there are 8 of them), number and letters, so not digits.

Why none of my codes worked? Would have it been necessary to generate a new set after changing password?
