Firefox Support Forum

I've tried to search and found some other posts about this, but not a ton... leading me to believe there is something wrong.

Issue: Fonts on some sites are too heavy/bold (vs appearing correctly on Chrome/Chromium browsers) Environment: Windows 10 or 11, Firefox stable (currently 105.0.1) Example site: https://www.subaruoutback.org (this is not the only one, just an example) Workaround(s): I can do one of two things... I can either enforce browser fonts globally, which fixes the issue but then also break some sites in other ways or I can use an add-on to let me selectively enforce browser fonts as needed (which is what I am doing).

Screenshots attached, this is my experience on multiple PCs (Windows 10 and 11). One image is from Firefox, one is from Chrome.

On some sites, it isn't a huge deal... maybe just looks bad but is functionally fine. On some sites the issue is more impactful and actually creates readability issues.

Of course I can continue to work around the issue, but ideally I would like to fix it.

I did read that there are some changes site owners can make for font handling, but obviously requesting that sort of thing isn't realistic in a general sense.

Thank you!

I have been having an issue for a week or more and no updates from the browser seems to fix that. The error reads: Bad Request Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit. This is occuring with a request to RBC banking. The same appears to be true but witrh different language for a request with Desjardins Insurance portal.The second link printed in red is the result after I cleared all cookies from Desjardins site. I can access many other pages within the two sites. RBC I am logged in (In black). Desjardins I am not yet as a user when these errors come up

Hello.

I have been unable to access product pages of a particular site, I believe, since updated to 106. The pages are viewable with Edge. https://www.officeworks.com.au/ The main page and some pages are fine but all product pages returns "Something went wrong". E.g. Office Supplies/Pencils https://www.officeworks.com.au/shop/officeworks/c/office-supplies/pencils?cm_sp=all:menu:office-supplies:::pencils I would like to know if this is Firefox's or the website's fault if so why.

Firefox 106.0.5 Windows 10 19045.2251

Hello,

Ever since upgrading to Firefox 107.0, I'm denied access to select website, some of which are corporate websites such as Nokia and others. The latest occurrence had the following reference no#:

Access Denied You don't have permission to access "http://www.nokia.com/phones/support" on this server.

Reference #18.9cf7df17.1669164130.8b3c1e51

If I employ other browsers like Safari or Brave, I'm able to successfully access both this page and others which are restricted on Firefox. So, what might be causing this to happen? Firefox is my preferred browser, therefore I'd like to find a fix. Any help would be greatly appreciated!

I'm not sure what happened in the latest update, but it broke the Canvas website that I use regularly for classes and homework. I've checked and confirmed that Canvas still works normally on Microsoft edge.

Extensions shouldn't affect the website because Canvas was working normally until the recent Firefox update.

Anyone know how to solve this problem?

Using my PC, I am clicking on this URL: https://schoolgateway.westminster.org.uk/?page_id=7. Firefox responds with "The requested service is temporarily unavailable. It is either overloaded or under maintenance. Please try later." Every time. Using Firefox for Android on my phone: same result. I have tried Troubleshoot Mode on my PC: same result. And yet Safari, Chrome, Edge and Brave all load the web page correctly with no error message.

What am I doing wrong?

So, for awhile now when I go to some sites, the screen suddenly starts flashing, then it jitters and turns some light color (like a light green; not blue screen, not black). If I guess where the "X" is to shut down the tab that has the video, I can end this. Often, like on youtube, I find the problem is some ad video that was playing. The rest of the site is ok. But not always.

One site I wrote down a few days where it happened: https://www.nbcsports.com/philadelphia/eagles/eagles-face-giants-2022-playoff-opener?cid=sm_npd_rsn_phi_fb_mn&fbclid=IwAR3rGUEa0W8fElrzCWANSIUpti9VKlbn0iHyvcFsviajYExo5tcRSyWBJXA

scroll down to video and everything blinks, becomes unuseable

It happens in lots of places, though. It is not per se a YouTube problem or just a problem at NBCSports. I shell out to MS Edge, and it seems to handle everything fine, so I'm assuming at this point it is a browser issue.

One last point: after this happen the screen display is degraded even after I manage to shut down the offending tab or video. It takes a Log off/log back in or reboot to fix everything. The degradation takes the form of making the screen look a bit like a pointilist painting, although that's an exaggeration.

FF 109.0.1 64 bit Windows 11 NVidia GeFORCE RTX 3060 running studio driver 526.98 (I have switched periodically from / to their gaming driver, which doesn't seem to matter)

Any help, appreciated.

Hello, This issue might or might not be related to [other issue] I have since I updated Ubuntu 20.04 to 22.04 and therefore updated my Firefox to 104. I can't login anymore on Letterboxd since the update. It's not a problem of username or password. When I click "Sign in", nothing happens except a page refresh, but I'm still not logged in. Other strange behaviour on that site since the update: most of the images don't appear. For example on this page : https://letterboxd.com/films/# all the movie covers are just blank.

The website does work properly when using Firefox in private mode though (both login and images work fine), so this makes me think it's related to my other issue mentioned above.

OS: Ubuntu 22.04 Firefox 104.0.2

EDIT after posting this question: I just found out that I can't login on Google either. I enter my username, password, then it asks me to validate on another apparel that it's really me, which I do, and nothing happens so I can't login. It works normally in private mode.

This site, Costco Instacart, worked perfectly with Firefox as recently as April 15, 2023 but today fails (see attached image): https://sameday.costco.com/store/costco/storefront?zipcode=11021

Cloudflare believes it is protecting itself from online attacks when accessed by Firefox. The same site worked perfectly today, on the same computer, using Google Chrome.

Cloudflare is a major CDN and many important commercial sites, like Costco Instacart, have their content delivered by Cloudflare so this is a major issue with Firefox. For the moment there is a work-around, use Chrome instead, but it would be better to have Firefox address issues with Cloudflare.

I have had 2 sites produce this error box in place of the target Web Site (See Picture). I have read previous topics about this and have followed the instructions with no positive results. FYI, clearing the web site's cookies, clearing Cache and disabling Hardware acceleration.

The first was https://www.walmart.com. After leaving a "Feedback" 2 weeks ago it appears as if they were able to fix the problem. However, the site is not as important as my Medicare PPO provider. I tried loading previous versions of Firefox, but that did not help.

In both instances the LOL "support" people's response was to try a different Browser. So, I reluctantly loaded Google Chrome and it worked perfectly. From my perspective, this eliminates everything to do with my machine setup.

Below is the sign-on URL (not unique to me). Please note that this 668 character URL has not changed for over a year. It is just Aetna's adoption of the Imperva Security Firewall. Both my Winders 8.1 and Winders 10 machines produce the identical results.

YouTube is blocking playback on Firefox due to my use of an ad blocker. However, playback is not blocked in the same circumstances when I use Chrome. Are they trying to stop me from using an ad blocker or overturn my browser choice by forcing me to move from Firefox to Chrome for playback with an ad blocker enabled?

• The attached image shows Firefox (on the right) not displaying Helvetica correctly. It appears jagged and not pleasant to look at. The browser on the left is Edge and all Chromium based web browsers seem to render it as it should.
• I've tried to look into (about:preferences#general) and the option that says (Allow pages to choose their own fonts, instead of your selections above) is ticked.
• I've also tried reinstalling the browser, clearing the website cache and also, removing my profile from it. None of these seemed to fix the issue.
• It's been persistent for quite some time now, however I didn't really find any articles regarding this issue.

  Any help would be greatly appreciated!

Expected: Firefox displaying all known Unicode characters.

Result: Many characters missing.

Failure page as an example: https://en.wikipedia.org/wiki/Religious_and_political_symbols_in_Unicode

Description: I tried going through a Unicode list Unicode list and the extensive set of characters displayed correctly. However, when reaching further into character sets as shown in the failure page page, many are missing which are not new.

• "Repair encoding. . ." button was not active.
• An encoding switch extension was not able to resolve the issue.
• Troubleshooting mode did not show changes.
• Switched fronts available such as Noto Sans and Roboto Sans without success. Possibly a font failure?

None of the menu buttons work at the top of yahoo mail in firefox when an e-mail is open, I am able to use these in Microsoft Edge. Until the last update of firefox they worked so something broke in the latest release 103.0.1 is my guess. I restarted without extensions and still broken.

I am getting Access Denied on many web sites that i have used frequently. For example, for the site https://www.apartments.com/ I get this message:

Access Denied You don't have permission to access "http://www.apartments.com/" on this server.

Reference #18.ca68dc17.1653685076.c42d150

I am using Firefox Browser 100.0.2

Help!

Lately in Google Drive I get this error when I select one image or a file: Impossible load details. Retry. I have Firefox 108 version, on Edge and Chrome all is OK. Also the troubleshoot mode doesn't resolve the problem.

Hi,

I use Firefox daily, but since the last update I'm unable to make card payments on websites and I'm having to use Chrome as a backup. Up until the update everything was fine and there were no issues making payments on the Royal Mail and Asda websites. When I click the pay button on these sites, the payment window does not open up.

I've tried disabling all addons/extensions to no avail.

Regards Andrew

I'm trying to use Microsoft Teams in Firefox because the native app for Linux is abandoned and crashes, and at first sight the app is blocking Firefox on purpose. Buttons to make calls are disabled, stating that audio and video are not supported in my browser, but everything works normally if join to existing calls using e.g. links.

Is it possible to trick Teams to think I'm using Chrome? I found the "User-Agent Switcher and Manager" add-on, but I can't figure out how to possibly use it.

Getting unreadable text when website is using a font that isn't installed (see attached screenshot). When I view the source in developer tools it uses Roboto (which I haven't installed).

On my Mac, I have tried other browsers (Chrome and Safari) and they work fine. I have also tried this website with Firefox on Windows and it also works fine.

When a playlist is loaded and played on YouTube, the next video in the playlist should automatically start playing once the current video reaches its end. This feature is commonly known as autoplay. However, I couldn't get it to work consistently. When the current video is finished, next video is loaded normally but where it should automatically play it doesn't.

I have tried below to address this issue:

• Autoplay next video works in safe mode.
• "allow audio and video" in autoplay permissions in https://support.mozilla.org/en-US/kb/block-autoplay doesn't help
• I have also set media.block-autoplay-until-in-foreground preference to false in about:config but didn't help
• I have tried uninstalling all extensions and it didn't help
• Tried logging out of youtube, but this didn't seem to help with the issue.
• Tried "Clear startup cache" in "more troubleshooting information" menu, didn't help
• Tried "Refresh Firefox" which didn't help

Thank you.
