Fóram Tacaíochta Firefox

As title- Cannot download for example webm format, but jpg is okay. cannot install any addon, theme or anything. DRM didnt install as well. i was trying reinstall, refreshing browser, rebooting.

I have recently been getting an error message when I open Firefox saying "The bookmarks and history system will not be functional because one of Firefox's files is in use by another application. Some security software can cause this problem". This has been happening since I clicked on a mail in Mail to unsubscribe from a spam/phishing mail list, which seemed to result in me installing Firefox Private Browsing, which I had never subscribed to. I have tried uninstalling Private Browsing but there is no way of doing that. I have even uninstalled and then re-installed Firefox completely but I still have the same problem. Because of the problem I have now lost all my bookmarks and history, and am unable to create new bookmarks and history. I have been on the help forums and seen that I can Disable Private Browsing by going through my anti-virus (Avast), which I have not yet tried because what I would really like to achieve is uninstalling and not having Private Browsing on my Start menu, rather than simply disabling it. Anyway, would disabling it solve the bookmarks and history problem ? Can anyone give me the solution ? Thanks. As you may gather, I am not very techno so you would have to give me the idiot's version of any instructions or advice.

I restarted my Windows 11 laptop and got error message about user profile. Restarted again and looks like it was corrupted so deleted my my user profile and Firefox config and bookmarks are gone!

Still have all the files just a new user profile and the old one is gone?

Any help how to get Firefox bookmarks back would be much appreciated

Hello, I've chatted with the creators of the add on "Twitter X Ad Blocker" and asked why it isn't working any more. They told me they have an update made and ready but you have not approved it yet. What will it take to get you to approve the update so this will work again?

Thanks, Tracy

for example: discord.com => discord.com/app

Is there any better way than adding a bookmark for it?

Hi,

So I got a new ultra-ultra wide 32:9 monitor and I noticed when I have firefox maximized on my new monitor and switch focus to a different window all of the text on tabs on the full screened firefox would go very blurry. If I had the same firefox windows full sized on my 16:9 secondary monitor this didn't happen. I then tried having the windows not maximized on the new monitor and it did not do this behavior when it was occupying what I would say was 1/3 of the screen width but if I stretched the screen too far it would again go back to this blurry behavior. So it seems like the text for the tabs behaves differently after the firefox window is stretched to a certain width. On the non-stretched firefox windows the letters simply get darker which I find to look better than the blurring. I added a screenshot that shows the differences I am seeing, the firefox window on the bottom screen shows the blurring, if you look at what would be the left middle side of the screenshot, while the top and bottom middle firefox windows show what it seems like it should look like.

Thanks, Dan

Hello! I installed Firefox about a year ago, and for the entire duration it seems about 60% of the time the default fonts on various websites look weird (bold?). I have tried uninstalling/reinstalling Firefox, clearing the cache, etc. See attached images for examples. Help!

tl:dr Here's the CSS to put in userChrome.css file. This is the "hides everything" option. See toward the end of this post for others.

1. navigator-toolbox:has(#PersonalToolbar[collapsed="true"]) {

 visibility: collapse;

}

I was looking for a way to hide the nav bar and ran across this older forum topic (https://support.mozilla.org/en-US/questions/1288181).

The solution shown here seems to be non-functional these days (early 2024), but it gets us in the right direction, so below is the code for us to look at.

1. main-window[chromehidden*="toolbar"] #nav-bar {

 visibility: collapse;

}

This is CSS, meant to be copied into a text document, itself placed in a folder called "chrome" that you'll need to create in your browser's active profile folder. Per step 6 in the instructions (https://www.userchrome.org/how-create-userchrome-css.html) linked by @jscher2000 in the above-linked forum topic, you'll also need to set toolkit.legacyUserProfileCustomizations.stylesheets to "true" in about:config. If you don't know what about:config is, this is a good example to get started, but I'm not going to explain it here.

This CSS code selects the object with ID #main-window, with an HTML attribute "chromehidden" equal to "toolbar", and sets its CSS property "visibility" to "collapse". Apparently Mozila have changed the way they implement toolbar hiding, as this no longer works — this chromehidden attribute is nowhere to be found in the HTML that drives the Firefox interface, not sure if that's the place to look for it, but I think so. Anyway, we need to dig around in this interface HTML ourselves to see what changes when hiding the bookmarks toolbar, so we can adapt a new method to what's going on in the browser now.

To do so, we open a window within a window (chrome://browser/content/browser.xhtml) and run the inspector via Web Developer Tools. Comparing the HTML we see here with the bookmarks toolbar in each state (I used BBEdit to compare the texts), we see that the object with ID #PersonalToolbar experiences a change in its "collapsed" attribute when we hide/show the bookmarks toolbar. So in our CSS code, we shift our strategy to update the "collapse" CSS property for #navigator-toolbox whenever it contains a #PersonalToolbar object with its own "collapsed" attribute set to "true", which occurs whenever we hide the bookmarks toolbar. Somewhat surprisingly, this approach of updating the CSS property seems to auto-reset on its own when the "collapsed" attribute is set back to "false", which occurs when we show the bookmarks toolbar again. In other words, it simply toggles with the visibility setting of the bookmarks toolbar, and we don't have to write any further code.

If you're interested in hiding some other UI element when hiding the bookmarks toolbar, you can modify this code to do stuff like that (but to go beyond the below examples you'll need to suss out the object IDs, CSS properties, and HTML attributes — and maybe more, depending on what you're trying to do — on your own).

But for convenience, here's an example that hides just the tabs:

1. navigator-toolbox:has(#PersonalToolbar[collapsed="true"]) #titlebar {

 visibility: collapse;

}

Here's one that hides just the URL bar:

1. navigator-toolbox:has(#PersonalToolbar[collapsed="true"]) #nav-bar {

 visibility: collapse;

}

Since those are the only other two things in the #navigator-toolbox to be hidden, I suppose that means we now have all options on the table (at least the way I have the browser set up). Enjoy!

Hi all; the subject line pretty much sopeaks for itself. Lately (within the past few days), whenever I open a new webpage, the sidebar appears. Until now it would only appear when I wanted it to, but now it's doing it on its own and it's annoying as ****. I've tried everything I can think of to stop this, so I'm giving you all the outstanding opportunity to help me remedy this aggravation. Many great thanks in advance!

Hi need to get my old firefox back before installation of new version.

I have a subscription that allows for downloading of videos using a "DOWNLOAD" button that has disappeared after new version of firefox was loaded. also my antivirus application has disappeared. How do i put everything back the way it was. I'm using windows 10.

Please help

I have been using Firefox as my preferred browser on Windows 10 Home and Pro systems for a considerable time and have recommended it to many Windows and Android users.

Windows 10 Home ver 10.0.19045 has recently been unable to access many well-known websites due to

Secure Connection Failed - An error occurred during a connection to <website's https url> PR_END_OF_FILE_ERROR.

There are multiple reports of this problem from 2023 up into 2024 in Mozilla support and across the web, but no solutions. Curiously all of the problem reports mention Firefox not any other browser. Suggestions to try multiple fixes, but none have resolved the problem.

One posting on Mozilla Support marked RESOLVED says the problem mysteriously went away for that user. Lots of people still seem to be having this problem, so how about a fix.

I cannot download any files or any adons through firefox. I have tried every single troubleshooting method in the "What to do if you can't download or save files" article I have restarted my computer, I have refreshed firefox, I have reinstalled firefox TWICE, I have turned off my firewall and tried downloading a file, I have changed the wifi im connected to, I can download files on internet explorer just fine, I have tried a new profile, I have scanned my device for viruses (theres none), I have no idea what the troubleshooting mode is supposed to do because I cannot download files in that either. I currently have no ad-ons installed because of the refresh I dont know what else to do and why is my firefox doing this, it started yesterday.

It was working fine and now the past few days I can no longer login to my Fastmail.com account other than from my Windows 7 pc

So no one including Firefox can email me

Concerning "Dismissed Suggestions"> Restore Suggestions. The "Restore" button (circled in image) is greyed out & will not do anything when clicked. This behaves same in normal as well as private browsing windows. Thank you

I can no longer connect to X ray images using your browser. The links are in EPIC. The X ray system is eUnity. If I can no longer connect I will have to switch browsers.

Your browser says: Secure Connection Failed
