Diễn đàn hỗ trợ Firefox

When I use Facebook with my Firefox browser the site just has to many issues. The site keeps hanging up and just sort of stalls out when I try to access messages and notifications that I download from the site. I took the suggestion of clearing my cache. That did nothing. Clearing my history didn't make a difference either. Being this problem doesn't happen with Chrome or Safari, it must be a Firefox problem. So, what more can I do to make using Facebook with Firefox a better experience? Sure would appreciate help.

Hi all,

By "extreme" I mean an all-caps extreme.

Some bulletpoints:

• Tried deleting stored data of affected websites
• Affects articles on e.g. science.org and pnas.org
• Tested troubleshooting mode
• Tested against Edge
• I noticed that the references (bibliography section) loads one by one, very slowly
• Hence maybe has to do with the integration of GetFTR by the affected journals
• Disabling tracking protection didn't work
• Only thing that "worked" (isn't a solution, really) is disabling all scripting and just using reading mode, using e.g. "||pnas.org^$stylesheet" in uBlock; doing that, the papers load in an instance

Example article: https://www.science.org/doi/10.1126/science.aeb1157

I first went to bugzilla, but read: "please consider checking Firefox Help instead of creating a bug", plus I don't know what technical stuff to submit.

If it isn't a configuration issue on my end, then I leave it in your good hands!

The Merrill Lynch login screen does not appear. Ad blockers are disabled; the problem does not appear with other browsers. Screenshots are attached for the same site using FF and Edge. I asked this question a few weeks ago but never got an answer. I'm using FF 153.03 64-bit

After clearing my cache, I got logged out of all of my accounts, and I can no longer sign into Google. When I enter my username it gives me a message that says “Couldn’t sign you in: this browser may not be secure. Try using a different browser.” I was able to log in using Chrome so it’s definitely not a device issue. I already tried clearing my cookies and cache again, and disabling all of my browser extensions, but I’m still getting the same message. Any help is appreciated!

Editing to add, I'm using Windows 11 and Firefox version 153.0

Hello,

Noticed a random problem over the last few months with Firefox currently running Mac OS 13.7.8 and Firefox 153. Problem started a few version back with Firefox.

I use gmail while viewing emails in FF I will click a link, tab to review information and I receive ---

Looks like there is a problem with this site 400 bad request. site could be unavailable or busy try again later.

I then proceed to another browser on the machine - Duck Duck, Chrome, Safari and ever browser connects fine, so the problem lies strictly with Firefox as there is no problem with the connection.

I saw a few items to check on the internet but none resolve the annoying issue.

Can anyone advise a solution before I decide to move to another operable browser.

Thanks, Bob

I can't download some pdfs, notably my bank statements. I CAN download some pdfs. Eg, I can download my car manual (although it's a process of downloading it to my Google Drive). However, trying to download my bank statements, Firefox gives me no options at all, and, indeed, I get an error message. Yet I CAN download my bank statements using Google Chrome! I've carefully checked all my Firefox settings, but nothing seems to address this problem. I've spoken to my bank, and they don't know why I can't download them either. When I try to download the statements, I get a screen saying it can't give me a 'Preview' (see attached screenshot), but there's a 'Download button. When I click that I get a white screen with the 'error' message:

"No API key found in request. request_id: d52e0732a3d10a75b1ec58534845c15c"

(2nd attached screenshot.)

I have asked about this before on this forum, but to no avail.

Following is what I see on the screen:

Hello,

I'm seeking support to try to resolve an issue that has recently started happening. I can't be the only one who is experiencing this, so if this is resolved others can benefit too. I'm not a complete novice, but neither do I claim to be an I.T. expert.

I use my ISP's webmail service to access my emails. I'm aware I could use an email client, but I prefer to access via a web browser and have done so for many years. About a week ago, I was no longer able to sign in to my webmail. I thought it may be a problem with my provider, so I checked using other web browsers - Safari on iOS which worked and Microsoft Edge (using the same internet connection, same desktop PC) which also worked and continues to work without issue. I can only think it must be something wrong with Firefox? I can access the sign in page as normal using Firefox and select my email address, but after attempting to login I always get the same error message:

Sorry, we can't sign you in just now

Don't worry, it's just a quick pause to help keep your account safe.

Instead:

   Use a device you've signed in on before
   Try again from a familiar connection
   If you're on a VPN, switch it off and have another go 

Still stuck? If this keeps happening, get in touch with us (quoting reference IDF-12B) and we'll help sort it.

I have 2 extensions installed in Firefox - Adblock Plus and Ghostery. I have already added the specific URLs to the allowed websites list (first is the sign in page, second is what it redirects to):

mail2.virginmedia.com oauth.virginmediao2.co.uk

I have searched around for possible solutions, to no avail. Virgin Media advise only signing in on their main home page, but I've never done this as its just another step and extra unnecessary clicks. I don’t want to constantly be bombarded with news, offers and promotions every time I want to check my email, so I only use the direct webmail sign in.

I have tried clearing cache, cookies, etc. Then I tried to refresh Firefox, none of which worked. I also tried uninstalling Firefox, then using CCleaner to perform a clean up and registry scan to fix any possible issues, followed by a clean installation. To my surprise, I was able to sign in to webmail OK. However, the next morning, I got the same error. The only other settings I have tried tweaking is adding exceptions to turn off "Enhanced Tracking Protection" and "Block pop-ups and third-part redirects" on those 2 web addresses.

Any suggestions or options to try would be appreciated.

Has anyone reported this before? I am working as a contractor for a BigTech company. I am using an online platform/tool of theirs for several years now but after a recent update the work area doesn't show scroll bars anymore. That means I cannot scroll the editor window and can't go beyond the first page. This makes working (and earning money) almost impossible. As even for the tiniest edit I have to download huge tasks which is extremely time-consuming. An inquiry with my manager there indicated that other contractors on firefox experience the same issue. so they consider it a firefox compatibility issue of some kind. They gave me the advice to use Chrome, Edge or Safri instead. Well, I use firefox because I do not want to use Chrome/Edge... Don't know about Safari but my PC is on Windows... Any idea what can cause it and how to resolve the issue?

Has Firefox instituted a security setting that is interfering with commerce-related sites? Suddenly I can't log in to my credit union (gets stuck on "authentication" step), amazon.com (endless "transferring data" message during login attempt), and mutual fund sites (similar to amazon.com experience). These all are related to money/commerce. I've turned off Firefox's popup blocking and even explicitly allowed cookies for the sites. I did a Refresh to get rid of extensions that might be causing problems (even though there wasn't a problem a week ago on these sites). I've tried Firefox on a second computer for the credit union site and got the same behavior. Chrome has no problem with these logins, by the way.

www.blu-ray.com not opening. i tried all ways like uninstall, re-install but still it's not opening. but in chrome and ms edge it's working properly. i tried troubleshoot mode, clear data but still it's not working. it's happening in these few days ago

Turn off tracking, even put x.com as an exception and it still won't let me log into X. Other browsers will but not firefox. I have noticed login problems on other sites too.. even with it " off" ie: IT DOES NOT TURN OFF. Windows 10 system

Ever since upgrading to Tahoe 26.5.2 I've had issues with the way the screen and some forms work:

• some buttons/ icons don't appear
• some buttons appear but don't work (no response when you click on them)
• oddities like if you select the edge of a window the cursore ocon stays as an arrow rather than changing to a resize icon.
• the overall screen appearance is white making some information hard to read

I suspect this is more to do with the Tahoe upgrade than Firefox - e.g. the 'liquid windows' mean some folders change appearance; sometimes being transparent therefore you can't see them anymore. Anyone else experiencing odd/frustrating behaviour since Tahoe upgrade? Seems another case of too many 'clever' features with no value make the software too complex and fragile.
