Diễn đàn hỗ trợ Firefox

I used a siteblocker and i tried blocking about:addons, wouldn't allow it so someone tell me how. im literally trying to prevent myself from removing extension i literally jumped from one browser to another just to make this shit possible please.

I'm trying to load a temporary add-on on my browser, but when I click the button "Load temporary add-on", nothing show up.

I tried to look for errors in the console or debugging tool, but nothing. With snap, I removed with the purge option my Firefox and install it again, but the issue still appears.

Some technical details: Ubuntu 22.04 LTS Firefox version 101.0.1 (64-bit) Mozilla Firefox Snap for Ubuntu canonical-002 - 1.0

Various website that contain dynamic content are not being rendered by Firefox to display that content. This is happening with websites that provide transportation information and ticketing, including Amtrak and Peter Pan Bus Lines . It is also happening with a genealogical website, FamilyTreeDNA, on pages that should be displaying family tree information. Illustrations of two pages are attached. I have been able to access the information by using Opera on this same computer and operating system, and by using the same version of Firefox installed on a different computer with different operating system. I am not sufficiently proficient with website development to know or understand what type of dynamic content is being generated by these websites, or how Firefox interprets the content. My suspicion is that some Firefox setting has been enabled or disabled, but I do not know which one it would be.

Hello,

I am running Firefox v101.0.1 (64-bit) on Linux (Pop!_OS, installed as a flatpak). I am using the default system theme in dark mode, though switching to the Firefox dark theme or other themes does not change anything. When I allow the Menu Bar (File, Edit, View, etc.) to be present, the browser tabs on the next line are aligned correctly, going all of the way to the left. When I uncheck the Menu Bar, however, a gap appears to the left of the tabs. I have not seen this behavior on Firefox in other environments (Debian, RHEL, Windows), and I'm wondering if there's a way I can remove that gap. I have attached screenshots showing how the tabs are aligned with and without the Menu Bar.

Thanks so much!

Hi, Just installed Ubuntu on a new laptop, with Firefox. No add ons.

Have changed my homepage to www.duckduckgo. Have changed my default search engine to duckduckgo. In about:config my browser.startup.homepage says www.duckduckgo.

Have also changed browser.startup.homepage_override.buildID to www.duckduckgo.com and browser.startup.homepage_override.mstone to www.duckduckgo.com

But STILL, every time I start Firefox, I'm taken to google.com. Please cn someone tell me how to stop google coming up when I start Firefox.

Thanks, Ivan

i had a big problem with windows 10 action center (it won't open at all) only one solution was creating new Microsoft profile and move all files from one to another (including downloads documents desktop and whole appdata folder with firefox inside included)

and theoretically all works fine. I have my firefox account, history, tabs, favorites, theme and plugins, but they have blank icons and doesn't work.

is there any way to automatically redownload and reinstall plugins?

I would like to add that I have 3 browsers (profiles) and different plugins in each.

You can't disable firefox spell checking. Check your spelling as you type. Misconfiguration? Did you make a mistake somewhere? I'm not sure. I mainly use two types of IME, Microsoft IME and google Japanese input.

I recently closed and re-opened Firefox to refresh it. Now, when I download an attachment from Gmail, a pop up appears next to my downloads icon. How do I turn that off?

There is no userChrome.css in my profile.

If it needs to be created, where do I create it?

Yes, I searched for help. What I found was about userChrome.css to solve specific problems, but not what to do if it doesn't exist. Is userChrome still supported?

Thank you! Mark.

(Firefox 102 on Windows.)

Indicating the progress of a runnig download in the taskbar is ok, but when the size of the download is unknown, there is a fast animation, that keeps going and going and going. That´s very annoying, when you want to keep focused on a difficult issue elsewhere on the screen. (Sadly I have these 'endless' and slow downloads quite often at work - e.g. github.)

How can this animation be disabled?

I would happily lose the normal download progress if only this fast animation disappears.

In about:config I did not find anything applicable when searching for 'download', 'animate', 'progress' or 'taskbar'.

I reinstalled Firefox and made sure that I had unticked the data and history boxes, and declined the search suggestions. Nevertheless, the first attempt at entering a search immediately called up millions of the things. At Chrome, I have learned a sequence of eight clicks, whereby I can, for just that one search, avoid those hideous suggestions. If I could have a no-click option at Firefox, I would stay here. Otherwise, can you tell me how to uninst... no, I can first have another look in Windows settings. Looked through the C drive, but I recall now there is an "uninstall programs" facility in Windows. So, if you are able to tell me how to switch off the suggestions, I will stay at Fireofox. If not, I won't. I can remember a Google (or Chrome) person talking on TV, about 15 yrs ago, about this new thing they had (search suggestions) that everyone would love. Four or five seconds into his talk, I knew that I hated it, and have never moved a millimeter away from that position.

How do I restore the display of this vital information? Why was it removed in the first place???

Information that is missing: - Time elapsed since download began (and time remaining if file size is known) - Amount downloaded - Total size of the file being downloaded (if known) - Download speed

Edit: This is at least the case for downloads where the conclusion results in the file being opened, instead of saved: https://cdn.discordapp.com/attachments/628080126630035466/993530387601043557/unknown.png

Firefox v40.0.3 Windows 10 Pro x64

I downloaded the admx file from mozila website and tried to disable the Developer tools option but its not working and I'm still able to access Developer tool.

I'm using freshly-downloaded Firefox version 102.2 on a brand new laptop (Windows 11 Pro version 21H2), and every single extension is showing a "Installation aborted because the add-on appears to be corrupt" message when I try to install. I have tried checking for updates, quitting and reopening firefox, restarting my computer, refreshing firefox, uninstalling and reinstalling firefox, as well as any and all combinations of those. I've scoured these message boards and nothing is working for me. Please help!

I was trying to change Firefox's font size to 2, (in about:config) but accidentally typed in 22. Now the screen is so zoomed in that I can't use the browser at all. It's so close-up that the only thing it's able to display is the corner of the menu bar. If I try to access troubleshooting mode, I obviously can't, since it still will only show the corner of the page. Since it's the font that's the issue, and not an actual zoom option, trying command/control -/+/0 doesn't work either. I can't make the page wider, longer or pull it to the side to attempt to see other parts of the page, and I can't scroll down, up, sideways, anything. I feel like I've tried everything, and at this point I'm worried I'm going to have to make an entirely new Firefox account or something just because I mistyped one number, which I really don't want to have to do.

Feeling like a real idiot, please help me. Attached an image of what the page looks like whenever I open Firefox.

In Firefox setting i have selected the startup option Open previous windows and tabs in startup. Still, when i Exit Firefox it asks if i wan to close the tabs. I suppose it shouldn't? After closing and restart Firefox doesn't restore previous session as it should. Whats wrong with this setting?

Tell me how to reduce the size of buttons, tabs, and everything else BUT the fonts in my browsers. All of them have been affected. I've exhausted all of the normal "look in Settings and use your brain" options.

Is there any way to open the about:config page to a specific setting? I frequently toggle a particular setting on and off and would like a quick way to bookmark it for easy access.

I'm thinking something along the lines of: about:config?setting=media.peerconnection.enabled

Even better would be to allow a new value to be passed in as well: about:config?setting=media.peerconnection.enabled&value=true
