Can not access PDF on a specific website when using Firefox 101.0. I can access with Google Chrome. Was told by the website that "we recommend using the most recent versions of either Google Chrome or Microsoft Edge. Other browsers, such as Safari or Firefox, are not compatible and will cause viewing issues. Our best suggestion at this time would be to check and confirm that you are using the most recent browser version." I prefer Firefox, so does anyone have a suggested fix for Firefox?

Hi!

From one day to the next some pages started to display with ultra-thin fonts. This does not happen in other browsers (like chrome), only in my firefox.

Hello

After the latest Firefox update, 101.0 (64-Bit) for Windows, the text of our website can't be read anymore because it suddenly appears way too bright.

It worked since years before and still works with other browsers.

Is this a know bug with version 101 and might be fixed? Or is there any other problem?

The website is: link text

Thanks a lot, if someone can help!

Kind regards,

Wolfgang

This tab [ https://www.weatherforyou.com/maps/elmira-mi-interactive/45.06444/-84.85611 ] worked just fine before the last update (101.0 for W7), and now it doesn't. It should show a radar map of my local area. Just FYI.

When I log in to survey websites (e-rewards or one opinion), they get the neverending clock so I can't choose & take a survey. I get into the website & can do everything except for taking the survey. Works fine in Edge.

I generally go here https://www.tafesa.edu.au/ and select 'learn' and log in there. Now I just get a window saying 'Taking you to your organisation's log in page' and circling dots and it stays there forever. That window is, I think, from Tafesa. So it sounds like a Tafesa problem.

BUT: I use Edge and it all goes smoothly and I log in. Which sounds like Firefox is not handling something from that site.

Anyone got any ideas on what i could do to get Firefox working on this?

Hello, I haven't been able to get Firefox to work for 2 days, after completely uninstalling the program and installing it several times, it still doesn't work, the only thing left is a black screen and it doesn't respond, the strange thing is that in safe mode it works and if I close the user interface of my session PC and I open another, Firefox does work, but I don't know what the error could be, I already tried almost all the solutions on the web and nothing, the program is virgin without add-ons or extra configurations, also if I close it, the program keeps running in the background and you have to force it to stop with the task manager, I would really appreciate an answer

I've been using Firefox for a week now and every time I work on my clients WordPress websites they show this message after a few hours of working on them:

"Secure Connection Failed

An error occurred during a connection to 4everyoung.com.br. PR_END_OF_FILE_ERROR

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
   Please contact the website owners to inform them of this problem."

When this message appears I need to restart my computer for the website to load again, when I use the websites on Chrome they don't show this error but if this error appears on Firefox, the website also stops loading on Chrome until I restart my computer. I've realized that activating and deactivating plugins will make this error appear but sometimes I'm just working on the website normally. This doesn't happen on any other websites, only my clients websites that I manage. All of them use WordPress but some are hosted by Hostgator and others are hosted by Hostinger. I've followed the steps of every forum post out there about this issue, contacted my hosting providers and they have no idea as to what may be causing this issue.

Since upgrading to 101 I am unable to login to some websites. So far this has happened with two financial institutions. For these I have had to use another browser to login to them. What happens is that I fill in my login credentials and click the login button. The login button appears to be dead as nothing happens. Logging in to all other websites works fine.

Dear Colleagues,

I hope this message finds you well. We are facing an issue with one of our public site. This site working perfectly fine on all other browsers except firefox. The website loads perfectly but when we click on login or signup Following error we are getting when we try to login .Uncaught Sys.WebForms.PageRequestManagerServerErrorException: Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 403 We have checked all the code and settings from our side but found nothing . 'FYI this site was perfectly fine before version 85 but now we are facing issues with later versions'

My site that uses Twitch.tv iframes no longer works because the Twitch iframes are unable to access their own cookies. When attempting to take any actions in the iframes, they ask to log in, and when the login flow is completed, nothing changes, it continues to not have the login state transfer over to the iframe. I'm hoping this is unintentional as it breaks entire use cases of iframes. I have no need to access the cookies myself, just let the site that is being frames access its own cookies!! This is WITHOUT the new protections that are in testing right now, but those ALSO were breaking it. Now it is broken even with them turned off. I will be using Edge for the foreseeable future until this is fixed I suppose... Love Mozilla and privacy but this is broken, sorry.

‘My original Firefox browser will no longer open, so downloaded and installed new one. Is there a way to get my passwords and history. It was the browser that I had my email deliver to.’ I was able to download from my other browsers, but the Firefox one just won't open.

I've been using Firefox almost exclusively for years now, and it's always worked flawlessly - until recently! Now, when I log into my GitHub account, I can no longer edit and commit my changes.

When I click on the "pencil" on a rendered page, I am taken to the "edit page" where I can make my changes (in markdown), preview those changes (rendered in markdown), and then commit those changes. Beginning very recently (within the past few days), the preview tab is no longer functional, and I can no longer commit my changes to the file.

I've verified that GitHub has not changed their interface by logging in from my Chrome browser, and following the exact same procedure used in Firefox everything works as it always has.

I recently upgraded from ver 99 to 100, and now to 101.0.1. I recall clicking a pop-up immediately after the 99-100 upgrade that had something to do with cookies... sorry, I know that's lame, but it's all I can recall now. In any case, I am certain this happened recently.

Please help... I have to use Chrome for a couple of things already (my brokerage account at Vanguard for example), but I despise Google, and want to limit their spying.

Thanks,

Instacart webpage suddenly will not display/open on Firefox but can display fine on Chrome. Instacart App on mobile phone works fine, just won't open in Firefox. Any suggestions other than using Chrome? Firefox version 101.0.1 Windows 10. Was working fine until latest update installed this morning.

For some time now FF will not open certain sites that it used to, these sites all open and function normally in other browsers such as Opera. The most important being my online bank! I have contacted the sites involved and they cannot understand why. I have cleared Cache, cookies etc. I'm using FF 88.0 on Ubuntu. Can you help?

This problem is a combo of the site and the browser. Here is a page of the site that misbehaves: https://www.yucatan.com.mx/merida/2022/6/13/detienen-en-merida-profugo-de-la-justicia-en-estados-unidos-326494.html (and attached) Most pages on the site do not misbehave. The problem is that the body text is all jammed to the right side of the screen. I have tried clearing the Firefox cache, and sometimes that works, I have tried restarting in troubleshooting mode, but that does not change anything. Internet Explorer shows the same problem, but the Edge browser does not display the problem. I suspect the site is doing something funky that results in a problem on some pages for some browsers. That's really hard to troubleshoot!

I first thought this issue was contained to a single website and was the fault of their IT, but I have begun to experience this issue on other websites, and it does not occur on other devices also using Firefox. It is difficult to explain given that I don't have any idea what is actually happening, but hopefully I can make it clear enough.

For some websites that require a username and password, I will correctly login and pass authentication but then I will be booted back to the initial login screen, almost like the login failed. I only know that it is technically a log out, not a failure, because I have briefly seen the URL change like I'm logging out. I have tried uninstalling and reinstalling Firefox fresh multiple times on my Windows 11 laptop, but the same issue occurs consistently.

This happened when I was trying to login to the student portal for my university and when I was trying to login to my apartment's resident portal. Changing cookie settings or going into a private browser has not helped at all. I cannot tell if this is a bug with Firefox (maybe just on Windows 11?) or if there is some background setting that needs to be adjusted, but it is very frustrating. If this keeps happening, I would have to switch to a different browser, which would not be ideal.

Does anyone have any idea of steps that I could take for troubleshooting or any experience with similar issues? Any help would be greatly appreciated.
