Firefox Support Forum

I use layout.frame_rate 1 to block animation, and to replace painful partial scrolling with clean jumps. I can't use an intermediate frame rate, such as 3-30 fps, due to the seizure risks, or a high frame rate, such as 60 fps, due to migraines when hit by "smooth" animation, "ease in-out" animation, zooming animation, parallax animation, partial scrolling with one part of the window sliding alongside another, etc.

about:config involves some other frame-rate and frame_rate settings;

gfx.display.frame-rate-divisor starts at 1

layers.offmainthreadcomposition.frame-rate starts at -1

layout.expose_high_rate_mode_from_refreshdriver starts at true

layout.frame_rate starts at 0, which defaults to monitor settings; I've reset it to 1 (1 frame per second).

layout.throttled_frame_rate starts at 1

What are these and what do they do? I've tried looking them up, and see a bunch of posts about browser diagnostics, or *increasing* frame rates, or the like.

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

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??

Starting last night Firefox will not let me download anything. If I click on a download link, my Mac toolbar goes gray like normal, but no download dialog box ever appears. I have confirmed the dialog box isn't hiding behind any open windows on my desktop, and I have tried rebooting my system with no change.

Please help me fix this.

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.

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!

This again!

This was resolved about a year ago; now the problem is back, as of updating to Firefox 113.0.1 this evening.

Initially post-update the close tab button was in a weird, random place on the tab bar. I have adjusted the margins to put the button back where it's supposed to be!

I changed :

.tabbrowser-tab .tab-close-button {
  opacity: 0;
  margin-left: -4.5px !important;
  margin-right: 2px !important;
}

to:

.tabbrowser-tab .tab-close-button {
  opacity: 0;
  margin-left: -4.5px !important;
  margin-right: 35px !important;
}

to move the button back onto the left. That may seem like a drastic change but that's the lowest value I could find which produced the result I want.

However, it's not quite the result I want! As of updating to 113.0.1, the tab title itself now disappears altogether on hover.

I have tried to correct this in CSS using the .tab-text and .tab-label attributes, but without any luck so far.

Can anybody help me with this, before I'm forced to downgrade to Firefox 112?

Better yet... how about we just make this an option in Settings, as it should be?!

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.

Hi,

does anyone know what to do to make the background of the bookmarks icon and the reload icon the same as the icon with the site connection lock? I've exhausted all options in the userChrome.css and cant get the background to change. It's in hover state.

For reference I've added a couple of images, the first how the background is and the second how I would like it to look. I'm on macOS and latest Firefox 111.

Best regards,

Johnny

Hi, I accidentally allowed notifications (while using Firefox) from a particular web site only to find out that now I get numerous notifications regarding phony virus alerts, etc. I am unable to block the notifications.

I searched the web for how to block a notification from a web site, but have not come up with any solutions.

In particular, I went to about:preferences > Privacy & Security > Permissions > Notifications. The web site is set to Block, but still the unwanted notifications continue. Perhaps the notifications are coming from a different web site that seems to be hidden?

I also quit Firefox and restarted Firefox, but the notifications continue. I also restarted my Macbook Pro, but that didn’t help either.

Here is the link I originally clicked on, but I obviously wouldn’t want anyone to click on it:

https://duckduckgo.com/?q=!ducky+trialjuries&ia=web

I would be so grateful if anyone has a solution!

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:

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.

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.

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 ...?

Every time I enter a link to a google service, I see a notice that says "Your should be redirected in a moment..." and then I get redirected to the Stanford University website (https://pass.stanford.edu/signin.html). It is not a specific website redirecting me, but rather some algorithm is detecting a google link and sending me to Stanford University instead . For instance, if I paste in a link to a particular location in Google Maps, I will end up at Stanford instead. I have no idea how to fix this, but it makes me avoid Firefox and use Chrome because Chrome does not redirect. I would rather use Firefox.
