Ondersteuningsforum voor Firefox

Hi all,

I am trying to customize my Firefox on Mac because the tabs on top interfere with the menu bar, thus I only want tree-style tab extension to work on the side, with the tabs on top disabled.

I followed this thread: https://support.mozilla.org/en-US/questions/1184674#answer-1028260 as well as this clear guide on how to create userChrome.css: https://www.userchrome.org/how-create-userchrome-css.html When I tried to restart the browser, I seemed to have been logged out of my profile, with all customization gone and a standard white (instead of black) menu. I deleted the chrome folder and it is normal again now.

I suspect the userChrome.css file should contain more than just the one line I tried to add: #tabbrowser-tabs { visibility: collapse !important; } ; Is there any location where I can copy my current intra-browser customization into the userChrome.css file?

So I was having some trouble a few days ago with a website that automatically re-directed as soon as I landed on it to another page. So I happily went off in the settings and disable the automatic redirect. Now a week or two later I'm sitting here going I can't find the setting anymore? I can't even search for it and have absolutely no results you would think searching for "redirect" in the settings pain would bring it up. it's probably something that got buried in developer tools that I would never be able to turn off/toggle again unless I get lucky with the right extremely memorable and easily accessible incantation in the about : config because that's just all so well documented. Is it a "1" is it a "0" is it a "5" which one disabled / enabled what is the other options do?

How to disable: "Your internet connection was restored" notifications? – Terribly annoying and only started in the last version 77.0.1 very recently. I rather switch to another browser if I cannot get rid of this. Checked my 3 plug-ins, but cannot find anything there, nor if it is something on Facebook I cannot find it. Any idea?

The Firefox desktop browser is the only one that give me this error Error code: SEC_ERROR_REVOKED_CERTIFICATE I am on a MAC OS using latest version of Mozilla Firefox desktop browser: 82.0.1 (64-bit) Incognito mode, cleared everything, reinstalled the browser and still got the same error. Talked with GoDaddy support and they told me everything is ok on their side. What is going on? Why: Safari, Chrome, Opera, Firefox Mobile (iOS) and so on have no problem loading my pages, but Firefox desktop has?

I looked on my GoDaddy hosting cPanel and the SSL are correctly generated and valid, so I don't understand what is going on with this browser.

Thank you! PS - If this is already answered, please point me to the correct reply.

Hello! A site kept popping up a confirmation window for an action I was trying to take, and in the confirmation window, there was a checkbox for something like "don't allow [this website] to prompt me again" (that's as best I can remember). I checked the box thinking it would just allow the action to happen without the confirmation window, but instead, the site just won't take that action anymore. How can I undo this setting? Thank you!

I run FF on both a Windows machine and a MacBook Pro. On the MBP the browser does not save my tabs, despite "restore previous session" being selected. I do not have this problem on the Windows machine.

I have tried uninstalling and reinstalling the browser but it has not made a difference.

I'm running the latest version of the browser and the OS is Big Sur.

In the last week I've continually had the error message PR_END_OF_FILE_ERROR appearing in place of various websites. There's no consistency - one day a website can load fine, the next I get the error message, the next day it'll load fine again. And the problem seems to be getting worse... It's driving me mad! Please help!

So basically when I click “Play” on the Roblox website, it brings me to a new Roblox homepage tab. I know this isn’t really the place to be complaining about this, but I can’t find ANYTHING on Reddit, the Roblox forums, or any other help website, leaving the Mozilla forums as a last resort.

Hi! Netflix used to work great in Firefox on my Mac OS X 10.11.6 macbook. Now I've been getting an error message saying "Looks like your browser is no longer supported" when trying to play video on Netflix and it won't play. I noticed that it self-updated a couple times over the last few days but these updates did not solve the problem. I'm hoping that this problem can be fixed so that I can keep watching Netflix on Firefox, as I find Chrome and other browsers are very slow and laggy compared to Firefox. Thanks :)

Recently I have noticed that where there are drop down lists on websites I visit the drop down function no longer works properly if I am using the Firefox browser. If I click on the arrow in a drop down list box the list briefly appears then disappears almost immediately making impossible to select an option from that list. I don't have this problem if I use any other browser like Safari and the drop down list function used to work on Firefox, so presumably this is a bug unless there is something in preferences that needs changing. I am using v88.0.1 on mac OS Sierra 10.12.6. Any help wud be appreciated

I cannot get Firefox to go completely into full screen on Mac OS Catalina. When going full screen it will hide the Mac system menu bar at the top, but it will not hide the Firefox address bar. I've researched a bit and found some suggestions about settings in about:config pertaining to full screen access, and I've exhausted all of those suggestions. Is this a known issue on Mac with Firefox?

My present iMac is failing rapidly and I will be replacing it with a new Mac very. I do not have a Time Machine backup. The only info I really need is how to copy off, to an external drive, all the bookmarks and bookmark structure), extensions, and add-ons I have added to Firefox, and then add them to Firefox on my future Mac.

Do I just copy the Firefox app to the external drive? I looked in the Macs' base system Library and Preferences, and in my User files, but I do not see anything related to Firefox.

My old (current) and failing Mac is running the latest version of Catalina,

Thanks for any info!

Hello,

It's been a while since the release date of chromecast on browsers.. Today, year 2020, all the chromium based browsers add chromecast (Edge, brave, chrome, etc..). My favorite browser is firefox, and i am forced to use a chromium based browser to cast to my androidTV's. Sometimes i think to leave this browser and use a chromium based all the time.

I searched and installed chromecast extension to firefox and nothing works to me, and they are not user frindly as chromecast extension on chrome.

Can you tell me if you even think in add a chromecast extension in firefox by default?

Thanks,

How can I get a list of all the sites that are set to "always open" in a specific container? For example, I want to see a list of all the sites set to always open in the Work container. I would also like to edit the list without needing to manually visit each site.

My MacBook Pro is running OS 11.0.1 and using Firefox 83.0. My battery runs down faster than it used to. Apple suggested checking the Activity monitor and I noticed several instances of FirefoxCP Web Content. I have lots of tabs open. Most of them are using <1% of CPU, but one is about 50%. Is there any way to figure out what that is other than shutting down the tabs one at a time and watching the Activity Monitor?

Is there a way to set a web site as my home page and not have to reset it every week or so? Also, when will we be able to choose what web site is loaded when we open a new tab?

I have been trying to watch Netflix on Firefox, I made some security changes and at first thought that I may have caused the problem, but now I see that the add-on just fails to install. It just keeps the notification that it is installing. Is there a way to fix this issue?

When clicking on an article link in an email from Wired, "Header overflow" is the only thing that is displayed in Firefox. It worked prior to latest upgrade. The link works fine when using Safari.

Hello,

I'm beginner in development. Today I'm working on some CSS files.

But when I reload, the content don't load the new features. I've try to clear cache, remove stockage on the console , and also try command + f5 (on iMac).

The only one solution I've founded is to clear cache , leave firefox , shutdown computer and restart.

Very contraignant. I've test on Chrome and it work well. So I don't know what I need to do to...

I'm using MAMP to lauch app on local
