Thank you. I’m not a technical person and so could you please share the specific and safe steps which will resolve both the error state shown, and the TLS logging issue without creating any other unintended consequences. I don’t want create any additional problems while trying to address these two issues. Thank you

Hello,

For some inexplicable reason, when I visit any Wikipedia page (as of Thursday 8th October 2026), the pages display with a huge oversized font that also impacts the format and layout of the page in my browser. I have not made any adjustments on my PC to increase font display size. Wikipedia is the ONLY website that displays in this manner.

I am running Firefox 115.42.0esr (64-bit), which appears to indicate Firefox is up-to-date on my Windows 8.1 desktop PC. Please note that I am still running Windows 8.1 on this device out of choice.

I reported the fault initially to Wikipedia itself, and the response is that any fault is at my end. I have visited the same Wikipedia pages via Chrome Version 109.0.5414.168 (Official Build) (64-bit) and the pages display normally.

I have attached a sample screenshot to illustrate.

Any ideas how I can resolve this issue please?

Many thanks - Dean

You guys are doing really good. BUt I'm going to have to say- If it ain't broke don't fix it. Why change the shape of the grouped tabs icon??? Without having even a option to change it back or to something else entirely. Was there someone specifically asking for that appearance update? Can we as users have an option to not have that unpleasing, google-reminiscent* shape set for the grouped tabs? Please?

Firefox (currently 157) continually crashes on my Windows 10 machine. Task Manager shows Firefox downloading sub apps (currently, 11) until memory is full. Then Firefox crashes. Task Manager shows 11 sub apps open right now using 537Mb of memory. I opened in troubleshoot mode. If I open in normal mode, more than 1Gb will be used with 14 or 15 sub apps downloaded. Only two tabs are shown as being opened. This started with one of the earlier updates and newer updates didn't fix the problem. Even emptying the cache didn't help. Do you recommend totally deleting Firefox and starting over from scratch?

I am using Firefox 157.0.1 (64-bit) on Windows 10. When I browse papers on https://www.sciencedirect.com(https://www.sciencedirect.com) and click the "View PDF" button, the page that opens is completely blank. The same PDF loads normally in Microsoft Edge.

I have already tried troubleshooting steps: I cleared cookies for this website and disabled Enhanced Tracking Protection for [sciencedirect.com](https://sciencedirect.com), but the blank page issue still exists.

Thank you for your attention and assistance.

Is it really not possible to adjust the font size? I found no setting for that. I only can cheange the text size of webpages, but not for title or menueor other thing a the top of the firefox window. These are readable with thunderbird, but not with firefox after I changed to a new laptop with higher resolution. Size of elements should be measured in points, mm or inches an not in pixels, as pixel sizes are depending on HW. The attached image shows the comparison between thunderbird and firefox.

My system • Windows 11 on a Dell laptop. • Firefox Version 157, my default browser. • Norton 360 Standard. • Two Firefox profiles; the warning appears in both. • Firefox Troubleshooting Mode does not eliminate the warning https://support.mozilla.org/en-US/kb/sslkeylogfile-warning?utm_source=chatgpt.com

What I have observed The warning appears on Firefox network-error pages, including when the internet is disconnected or I enter an incorrect URL. A particularly reproducible example occurs after I successfully log in to Kotak Net Banking and select Help → Raise a Query. Firefox then displays a connection/privacy warning associated with the embedded page. I do not see the same behaviour in Chrome or Firefox Private Browsing when performing the equivalent Kotak steps. Troubleshooting already completed 1. Norton Safe Web HTTPS scanning was disabled and re-enabled without resolving the issue. 2. QUIC/HTTP3 scanning, WebSocket Protocol Scanning and DNS/DoH scanning were individually tested without resolving it. 3. Firefox Enterprise Policies are inactive. 4. I found no SSLKEYLOGFILE entry in either Windows User Variables or System Variables. 5. Norton and Dell malware scans found no malware. 6. The warning also occurs when I connect through a mobile phone hotspot rather than my usual BSNL connection. Questions for Mozilla's technical contributors 1. Does this warning establish that Firefox detects SSLKEYLOGFILE, or could another mechanism produce the same message? 2. Can the variable be inherited by Firefox from a parent process or injected into its running process even when it is absent from the Windows User and System Variables? 3. What is the safest way to identify which process or security product is setting it on Windows 11? 4. Is there a known interaction between Firefox 157 and Norton 360 Standard that could explain this behaviour? 5. What evidence should I collect to distinguish a Norton issue from a Firefox issue without disabling security protections or modifying Windows settings? I am not looking to disable security features indiscriminately. I want to identify the actual cause and, if Norton is responsible, determine the precise setting that needs attention. I would particularly appreciate a response from a contributor with Windows networking, Firefox TLS or security-software diagnostic experience. Thank you.

Hello!

I'm a Japanese user who recently started using Firefox, and I have a question.

I've noticed that Firefox's built-in translation feature is somewhat less convenient than those of Edge and Chrome, especially when I want to translate pages into my native language (Japanese) regardless of the language Firefox detects.

For some reason, when Firefox identifies a page as Japanese, it doesn't offer the one-click translation option, even if the page contains a lot of English text.

To work around this, I have to click the ≡ menu on each page, change the source language from Japanese to English, and then change the target language from Japanese to English.

Does anyone have any ideas for making this translation process smoother?

Any suggestions would be greatly appreciated.

Thank you!

I am trying to change my default search engine to Firefox and it isn't allowing me. What could be preventing this? and how do I get around it? Thank you in advance for your help.

Title. 156.0 had NVIDIA Video Super Resolution working just fine. 156.0.1 has broken it on my setup. Nothing I have done has brought it back - toggling settings, clearing caches, forcing it on in about:config, etc. The plugin seems to be broken.

Was working just fine for over a year prior.

Latest Stable Firefox 156.0.1 RTX 5080 Driver 596.49 (May '26)

Does not show as working in the Control Panel, and is clearly not working on any video site. YouTube, the BBC, and Twitch were the ones most tested.

Please consider a fix. Thank you.

We often encounter this situation: both at home and at work, I don't want the Firefox password and browsing history on my home computer to be synchronized to the Firefox on my work computer. After all, there are many private passwords and browsing histories involved at home. However, the passwords and browsing histories related to work can be synchronized to my home computer, so that we can continue to view the records from work at home However, I haven't found this function anywhere in Firefox

Not a bug report, but more so a feature suggestion for extra keybinds. In case this isn't the right place for a feature suggestion, please excuse me, since search results only yielded the Firefox suggestions thingy. Some browsers like Opera have a keyboard shortcut assigned to selecting the website URL through Cmd+E. This is pretty convenient for those who access most of the browser controls using a keyboard rather than a mouse or touchpad. At the moment you can use "Focus the Search Bar" by Cmd+K and Esc twice to have the URL selected but it's not really ideal. Thanks for the continued support and making Firefox a great browser to use.

I'll be blunt...: the new Nova interface is impractical, uncomfortable to use, and I find it genuinely hard to stomach. On a touchscreen, hitting the right tab has become a struggle. With a mouse it is no better — there are now dead grey zones where a click simply does nothing at all. This is not a matter of taste. This is a measurable usability regression, and it shipped to everyone by default. I am not alone in this. The same complaints are all over the forum, and my own students were furious when their terminals updated and everything suddenly turned round. These are people who use this browser for work every single day. For them the update brought nothing but lost time. We like Firefox. We want to keep using it. That is exactly why this is so infuriating: a browser we chose for its control and configurability is now imposing a design decision on us with no way out.

If nothing changes, we will solve it ourselves — with a patch that suppresses update notifications and adds a "Manual update" option to the settings, so that people have a CHOICE and can keep working in the good old rectangular Firefox UI instead of having someone's "brilliant" idea forced on them. I would much rather you simply gave us that choice yourselves.

Please restore a usable, compact, rectangular tab style as a supported option, and fix the dead click zones.

Respectfully, A concerned user

I synced the wrong Firefox profile to mY Mozilla account. I hence deleted the account to get a reset. But now I can't sync any more, because I get the message: your profile was previously synced to a different account, create a new profile. How can I activate sync again?
