Firefox Community Forum

Hello! My Firefox browser is currently in a state where all fonts/letters in the Firefox interface (bookmark bar, settings, about page, website name...) are replaced by undecipherable characters.

I've searched for similar problems already and tried so far the following steps to resolve, unsuccesfully...

• Opening the browser in Safe Mode / Deactivating all extensions
• Uninstalling and reinstalling Firefox

• Disabling hardware acceleration
• Trying on another profile




When I copy paste said text to another window (ex: Notepad, Chrome Browser…) it appears properly. And as you can see in the screenshots below the text in actual websites is readable -- only the browser's interface, setting, address bar... are scrambled.

Does that bug rings any bell? Do you have any other troubleshooting steps I should try to resolve this? Any help will be appreciated! : )

How do I get Firefox to stop flagging Canadian spellings as wrong when English-ca is my top preferred language in settings? I am writing a WordPress post using Firefox on Mac.

How do I get my apps, like Duolingo, Facebook etc. back on my Firefox page? I just perhaps, made a mistake, and downloaded the new Mozilla/Firefox page and now I don't see my apps that I use everyday. Help!

You say, "Some essential Mozilla services are excluded from VPN routing to ensure sign-in, VPN reconnection, and screens needed to sign in for public Wi-Fi work properly. All other browsing activity in Firefox remains protected when the VPN is on."

How then am I protected in any kind of secure way?

All it would take is the Mozilla services using my public IP to lose my browsing protection. How are those connections secured to protect my identity from being exposed once the VPN is enabled and even after the VPN is enabled?

If the public IP can be discovered at sign-in, re-connections, and public Wi-Fi connections before the VPN is enabled, then that same public IP can be traced through internal logs to uncover all the VPN activity done after sign-in, re-connections, and public Wi-Fi access. So, how exactly can I trust the VPN protects my activity at all?

I'm just curious how you setup any protection prior to the VPN being enabled? I'm a former IT Network Specialist I had my CISCO CCNA certificate (Worked in school districts who wouldn't pay for additional certificates so I did all the study work and practice testing up to the CCNP certification just could never afford to take any of the exams beyond the CCNA). So, when I see these additional things like your 50 GB of free browser VPN and read how it works I get curious about the actual protections being provided. Are the people more vulnerable than they may be led to believe?

OK - this keep happening on my firefox browser on my macbook laptop. I have a default firefox browser open with my 13 default tabs. Now when I have some app, like today specifically, the app for my voice caddy golf app. I open the app, do the update, and if I select any link that opens the voice caddy website, it opens it in a new firefox browser and tab, NOT a tab in my existing firefox with my 13 default tabs. So my default firefox gets trashed. In my firefox settings, I told firefox to open any new tabs in tabs, NOT pages. I also have open the last tabs open where I left off when I close firefox. What a pain. Tried several things to no avail. Why doesn't firefox have a setting (or the current setting do as I told it - open new websites in a new TAB, NOT a new browser.

Since version 154, my 2017 Macbook Air running MacOS Monterey causes my fans to be always on. The battery preferences says "Using significant amount energy." I've turned off all AI features.

I'm the only User of my Firefox browser and I noticed Firefox stopped filling out logins automatically when browsing on the internet. I was unable to access my logins in the preference menu under "manage saved passwords" as the list was empty. At first I didn't understand why. It seems that I hadn't created a "Profile" and was still using Firefox with my main account and as such was unable to access any previously synced data of that nature (under the updated Firefox configuration) I have now created a Profile but I don't know how to sync with my main account's login data list... I have read that I can locate a Profile folder to load previous data, but I'd rather find the main account folder if that's even possible, because the Profile folder hasn't synced any logins if I understand correctly.

Cheers for even reading this far ;)

Hi All,

I had several tab groups. I open and save and close them every day. but since yesterdayI cant find them at all. If I create a new tab group it appears but those old tab groups not! I've tested troubleshooting mode but noting.  

Firefox 154.0 (aarch64), macOS 26.6.2.

When I try to get to the SSA website it looks like my account is open but I can not sign out or in. It continues to give me this message. "Bad Request Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit."

I can sign in with another browser. I have used chrome or safari.

Can you help me out?

For some scrollables, v153 doesn't respect the Mac OS setting to hide scrollbars unless scrolling on page load. If that OS setting is adjusted after the page is loaded, then the page respects it again until refresh, so there's apparently some sort of race condition going on where it's not reading the setting in time before the page loads?

This is not a problem in v152. I downgraded back to v152 and it's working again.
