I have dealt with this tiny font problem before but did not retain the fix because I actually thought I had solved the problem once and for all.

BUT, I wake up this morning, having made no changes to this laptop overnight, only to discover that the fonts on my Firefox browser controls are tiny tiny tiny.

I expect Firefox/Mozilla to resolve this LONG-STANDING problem once and for all. I have made no changes to this browser in the last 24 hours. There were two MS updates that occurred overnight, but I doubt this affected the fonts on the Firefox application.

If there is a straightforward FF/Mozilla doc that addresses this problem (since it is recurring and well documented by others over the years), I would appreciate a link to this document. And if there is a known problem with certain MS updates I would appreciate knowing about this as well.

TIA

In other browsers when I add extensions, I can open an extension panel, or got the the browsers installed extensions section, and edit open up my extension setting pages, and edit them. For example uBlock Origin, but there are others. It doesn't seem possible to do such a thing with Firefox. Is that on purpose or is something wrong?

Hi there!

Is there a way to define the view in which pdf files are opened by default?

When I open a pdf file it opens in "Automatic Zoom." Is it possible to set pdf's to open in "page width" or a different zoom setting?

Kind regards

It would be great if FF could support multiple dictionaries depending on the detected language of the typing. More and more of us are using multiple languages, and I think it's a real benefit for FF to support this feature.

I'm digging up this topic because I'm very interested in this feature (and I think many are).

I tried to create a default Windows profile with pre-configured app settings, including FF. I created a temporary user, logged in, installed FF and configured it, also installed some add-ons (first of all, ublock origin). Then I logged out, logged as an administrator and moved the temporary user profile to the default profile location (c:\Users\Temp -> c:\Users\Default), and then reset its NTFS permissions. This almost always works for all applications, including Google Chrome. I created a new user and logged in, opened FF. The settings were applied, but the extensions did NOT work, and even the buttons on the toolbar looked like empty squares. At the same time, the add-ons were present in the list of add-ons in settings, although without icons. It helped to turn off and turn on all the add-ons one by one, manually.

After some research, I realized that FF binds its settings to absolute paths to add-on files (*.xpi), specifically in the $profile/extensions.json and $profile/addonStartup.json.lz4 files. Google Chrome, for example, doesn't do anything simular, like the vast majority of applications. Removing these files from the profile will cause all add-ons to be "reinstalled" on first launch and set to a disabled status.

An easier way to reproduce the problem: 1. Run firefox -profile d:\temp\profile1 2. Install some extensions. 3. Rename profile1 folder to profile2. 4. Run firefox -profile d:\temp\profile2 5. Got it!

For what purposes does firefox bind to absolute add-on paths, and how can this problem be solved? P.S. I know about portable firefox from PortableApps.com, but I don't want to use a third-party loader for my tasks.

A few days ago I changed to a new computer.

On my old Windows 11 computer in Firefox I could sign in with my [edited] @gmail account to my Blogger blog, see the New Posts page, edit my posts, post new posts and see the sign out option.

But on my new Windows 11 computer in Firefox I can sign in with my [edited] @gmail account to my Blogger blog, see the New Posts page, but I can't edit my posts. I am signed in but Firefox doesn't show the sign out option.

Whereas on my new computer in Chrome I can sign in with my [edited] @gmail account to my Blogger blog, see the New Posts page, edit my posts, post new posts, and see the sign out option. As always.

In Firefox it says there is something wrong with my [edited] @gmail account and to refresh it or change to another account. I don't now how to refresh it and changing to another Gmail won't work. But it lets me in to my blog's New Posts page!

How can I in Firefox on my new computer edit my posts and see the sign out option, as before and as always in Chrome?

I'm trying to add the zscaler certificate (my company uses it) to firefox using the certificate manager. When i select the certificate and click import, nothing happens. The certificate doesn't show up on the list of authorities and there are no error messages.

I'm using firefox in a VM running Ubuntu btw and the certificate I exported from the host machine running Windows.

I haven't figured out how to get Firefox to fill in Verification Codes when logging into web sites that require such.

Can you provide steps to this feature?

Hello,

It's been a while I wanted to try vertical tabs and now is is possible with FF. I was wondering if it is possible to merge the two top rows when using vertical tabs ? (The address and buttons row and the Windows, minimize, resize and close row).

When using horizontal tabs, the top row (minimize, resize and close row) is merged with the tabs row. But when using vertical tabs, you can a "useless" row that takes almost as much space as the horizontal tabs row, so vertical tabs doesn't make you gain that much browsing space.

Thanks

Hello! My computer is Win 7 (my system info; the same with greater detail). I've been relying on Waterfox (mainly to download videos; it's not the browser I use regularly) for years, and it has never given a problem, far as web access. I have not updated the browser, main reason being my downloading add-on (which happens to be the popular "Video DownloadHelper") behaves in a less preferred way in my other browsers. (I fear an update would put the kibosh on the better way that program functions in Waterfox.)

Suddenly Waterfox has become moody (I don't know if BB code is going to work here, but the following image is a scrrenshot of "Hmm. We're having trouble finding that site." If not showing below, the direct link.):

[URL=https://imgbox.com/hXEimf6M][IMG]https://thumbs2.imgbox.com/62/ca/hXEimf6M_t.jpg/IMG/URL

I am hoping the ones reading may have suggestions for me to get my Waterfox back.

I did install a VPN recently, but I don't think that's an issue. Another point of consideration: Waterfox can access the internet in Safe Mode.

I consulted this handy-dandy page before bothering you:

7 Fixes to Try When Waterfox Is Not Loading Webpages on Windows

1) Weak internet connection. (Nope.) 2) Corruption in Waterfox installation files. (This possibility seems remote. After all, it was working well until now. ) 3) Malicious extensions (I have tried disabling all extensions, and there aren't that many.) 4) Webpages will also fail to load if there's something wrong with the browser's code. (This "code," whatever that is. was working fine for all this time. A quick look-see led to this meaning of "code": "..Code is made from C++ and C. Also javascript, pyhton, ruby, and many other languages." That seems to be a long shot.)

Their recommendations (leaving out the ones that are not relevant):

2) Update Waterfox. (I'm trying to avoid that. Of course, this might be the solution; however, It's not as though my version is that old and would have stopped working. Of course... who knows.)

4) Check Your DNS (Sounds like a lot of trouble; I don't think this will make a difference, as other browsers present no problem, and WF works in Safe Mode.)

5) Clear Waterfox Cache and Cookies (I did that.)

6)  Remove Unwanted Extensions  (I did that, by disabling the toggles, as suggested.)

7) Reset Waterfox.

That might be the last resort, and I have the feeling a reset is not going to do the trick. Doing this will get rid of the video downloading extension I'm trying to preserve, and instead I'm hoping one or more experts might come up with another suggestion that will work.

As an additional point, under Waterfox's "Options" > "Network Settings" > "Settings," where the default choice under "Configure Proxy Access to the Internet" is "Use system proxy settings," I fooled around by checking the first two, "No proxy" and "Auto-detect proxy settings for this network," and neither selection did anything. I could not try the remaining choice, "Manual proxy configuration," because I have no idea what figures or numbers to place for that one. If the BB code for the screenshot below does not show, here is the direct image; I'm also using the "attachment" option below.

It's really odd Waterfox suddenly stopped working; it was so reliable.

Thank you. I would be very grateful for your help.

How to change home page and new tab to desired URL or any extension of Firefox desktop in 2025?

I am unable to find any way to change how my new tab should look when I click + sign or new tab is opened up on browser opening or re-opening unlike Chrome.

I hate the change of position of typing from the search bar on the current new tab to the URL bar (unseen or unheard in Chrome) that Firefox implemented without considering users who would detest it.

Using Firefox 131.0.3 (64-bit)

How to search for installed (both enabled and disabled) addons extensions in Firefox browser like chrome does via "chrome://extensions/" in 2025?

It is quite surprising that in 2024-25, firefox still doesnt have any option to search for installed addons via "about:addons". You can only search for addon site, not for those installed on your device and profile and browser.

Is firefox team really updating their browser for 2025 when compared to chrome?

Firefox 132.0.1 (64-bit); Fedora-40; Gnome. I just added the "authenticator" extension (https://addons.mozilla.org/en-US/firefox/addon/auth-helper/?utm_source=addons.mozilla.org&utm_medium=referral&utm_content=search). I would like its icon to appear in the toolbar, along with those for NoScript, Simple Translate, and others. I tried following the instructions on this page: "https://support.mozilla.org/en-US/kb/extensions-button". But clicking the "gear" icon in the toolbar brings up a list of all installed extensions, and there is no "gear" icon next to any of them.

How do I add the "authenticator" extension's icon to my toolbar where the other extension icons are?

I know I can hide the sidebar by clicking the button on the toolbar. But I'm used to opening my bookmarks and history with ctrl+b and ctrl+h, and being able to close them the same way. This still works to close the actual bookmarks/history, but the sidebar doesn't return to being hidden (despite being hidden before I opened them), it hangs around taking up space on the left of my screen. Even after I removed everything so it's just a useless blank rectangle with "customise sidebar" at the bottom, it defaults to staying open unless I click the button. It's really annoying. Is there any way to make it hide itself again automatically once I'm done using it?

A sidebar has appeared out of nowhere. I removed all extension on that sidebar and it still doesn't go away. I already have a bookmark bar and extensions at the top bar. I don't want another sidebar at every firefox window. How do I remove the sidebar, please.

Currently, and for some reason there seems to have been a change that's occurred because my browser seems to think I'm out of the country (USA) as my searches return "We don't ship out of the country." How do I tell my browsers that I'm in the USA?

The Support forum is full with people having this problem and it seems no one at Mozilla can even b.u.t.t in with something like "we are working on it" or "here is how you can fix it yourself, also for none nerds" or anything?? Hello Mozilla, are you still alive or should we move on to a browser that does not malfunction on such an important issue as copy and paste? P.S. no answer is an answer too Mozilla, we can safely assume you are now buried on boothill, right?

Can someone please tell me how to disable the new Sidebar? It is interrupting all of my workflow on the screen and it is frustrating with all of the choice and customization options in Firefox, that there would be no way to disable it.
