Firefox Community Forum

Sites struggle to load a lot of the time now, sites like youtube don't load until I clear my browsing history and cookies, some sites don't load at all, some shops don't load any image previews. I've tried on other browsers when these things happen and they don't happen there.

I have logged into TinyURL.com MANY times using Firefox. Now, I get a Cloudflare Validation Error when trying to do so (see attached screenshot/snip).

This was done in Troubleshooting mode, but is the same in standard mode, though I have no extensions enabled. I've tried turning Protection Tracking off; no luck. - We use ZoneAlarm, but the Web Secure functions are all disabled. - I have the same issue on 2 PC's, one Windows 10 and the other Windows 11, 64-bit. - I'm on FF release 150.0.2 - 64-bit, and both Windows installs are fully updated and kept that way. - I've reached out to TinyURL in hopes of resolving the issue. They suggested many of the above steps but not resolved this issue. - HOWEVER, I've found that login via Google Chrome IS seamless - no issues.

What is it with Firefox that it's having issues with the Cloudflare "Human" check? I've checked the Cloudflare site; all conditions are good, and this very setup passed the "Turnstile" check.

FF is my #1 preferred browser, so please look into this. I see that others have posted similar issues over multiple years here (but a search of support articles didn't find one . . .)

Thanks,

I can't access two websites in Firefox, but I can access them on my phone and in other browsers. One site is Facebook, and the other is https://www.gildertech.com/forum/

Thanks in advance,

I have various sites that won't accept site login credentials but work on other browsers and Firefox is running very slow. If I completely shut down and restart my computer, the logins will work for a few minutes but then stop working again. I've completely uninstalled Firefox several times, deleted my profile and created a new profile. Ran Firefox in troubleshooting mode with extensions turned off. None of these have had any effect. I recently saw a post that this might be a Firefox issue with version 154.00. I'm currently running version 154.01. Is this actually a Firefox issue or do I need to continue to look further into my computer and router for the problem?

bei Ebay werden die angebote falsch angezeigt, zum bespiel kann ich nicht sehen da eis ein Preisvorschlag ist. nach löschen der cookies auf der seite ist die ansicht richtig und wenn ich mich eingeloogt habe ist wieder alles falsch, echt nervig.

My desktop Firefox (version 155.0.1) has recently became unable to consistently access the Web site at this Web site this Web site. Chrome successfully accesses the site 100% of the time. Firefox's connection failures are intermittent, unpredictable, and usually go away on their own after varying time intervals (sometimes can't connect for up to 24 hours). I see status messages saying Firefox is trying to connect to the site, but it eventually gives up and times out.

I cleared the Firefox cache, but that had no effect. I don't recall making any significant changes to the Firefox settings lately. Any suggestions on what to look at/try would be greatly appreciated.

(Yes, I know the site doesn't use https: Its protocol is outside my control).

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?

Hi!

We have a intranet site that works in Edge and Chrome without issues with the site added to "internet options". But for some reason we are getting 401 Unauthorized when trying to access it from Firefox. I have tried adding the urls to: network.automatic-ntlm-auth.trusted-uris network.automatic-ntlm-auth.allow-proxies: true network.automatic-ntlm-auth.allow-non-fqdn: true network.auth.force-generic-ntlm: false network.auth.force-generic-ntlm-v1: false

Ingocnito mode , same error. I have tried disabling all plugins. Disabled DNS over HTTPS.

For some reason, my Gmail page doesn't show the icons on top at all. Like the archive, mark as read, and the others on top of the mailbox contents. They show up on both Chrome and Edge, so this seems to be a Firefox problem.

Computer being used with issue: HP ProDesk 600 G2 DM (Windows 10, 16GB RAM) So can this be fixed or should I just use my phone for Gmail?

I am suddenly finding I cannot scroll a thread in Chatgpt! What changed in the last 2 days? It has been working fine for 2 years. I am on OS mojave 10.14.6 on a 2015 Model Imac.

... click on (eg.) 'Interactive Map' and nothing happens, at least not here. Chromium has no problem.

Здравствуйте. Я установил сертификаты по инструкции, которая лежит на s.sber.ru/70VQ2B . После этого в мозилле не прогружается полностью окно входа на online.sberbank.ru, не видно содержимого фреймов (сейчас попробую сделать скриншот). В Microsoft Edge работа нормальная. Удаление сертификатов, перезапуск браузера и компьютера не помогли. На других компьютерах ещё не проверял. Посоветуйте, пожалуйста, что можно сделать. Windows 10, Firefox 153.0.3 (64-разрядный).

Depuis Firefox 150 il ne m'est plus possible de Glisser-Coller un dossier avec ses fichiers dans un dossier de mon NAS Synology. Le service d'assistance Synology m'a apporté confirmation. Voir sa note en attaché.

Il semble qu'il y a un "bug" dans Firefox 150 et plus (j'ai le 155.0.1) pour ce Glisser - Coller ?

Que puis-je faire ?

I'm on 153.0.4 (64-bit) and after the last update, drop-down arrows are non-functional. I use Firefox at work and the dashboards that I've been using can't be used because I can't make selections. I'm having to use Microsoft Edge (yuk).

Is there something I can do to restore the drop-down behavior?

Thanks, JR

suddenly have to pass a bot test using drum sounds or weird images before I can get to my email. I've been using Firefox to access email at att.yahoo.com for many months with no problem. Now I cannot get in. My idea of snare drums is obviously not the right answer. the weird images are worse. I've cleared the browsing history and cache per the instructions and it didn't help. ATT said it was because updates were done--or not done--to Firefox that caused the problem. When I pull up settings, it says Firefox is updated automatically and I'm up to date.

 so do I just give up and go back to Edge?

Thank you for any help (I am not Luddite, but not a tech wizard either--so detailed help would be great!)
