I have a Ruby on Rails app and whenever I click on a button in it that submits a POST request, instead of redirecting back, it sends me to a GET of the POST request. For example I am at /a, I make a POST request to /a/b, instead of redirecting back to /a, it sends me to /a/b which returns a 404 as there is only a POST defined at this route. I have tested this same site in Chromium and the redirects work properly, returning me back to /a

Hi Can't enter text in a site message box.

Message box appears okay after a link render and isn't a pop-up. Other routine Firefox fields work fine, any site. Works fine with my Chrome install. No cursor in the box but all other box elements interact with the mouse, like format buttons, help, resize, colour palette, etc.

Never seen this behaviour before and I have no ideas. Just moved to 64bit v150.0 on Win10. Thanks Dale

saw a post that recommenced to installing K-Lite Codec Pack would help so that i could set 1440p on Twitch because the option is greyed out for me. after installing it, twitch gets hung up and never finishes loading. it loads in a private window, and on edge too. i turned off the few extensions i have but that didnt help either.

i uninstalled the codec pack but im still getting the issue.

if i hit F12 i see theres an error Loading failed for the <script> with source “https://assets.twitch.tv/assets/6411-9f5e77558af00b1acec0.js”.

thnx!

I just got a new Dell Windows 11 desktop PC to replace my old Dell Windows 10 PC. Since switching, there are three sites that will absolutely not load the homepage: Paypal, Venmo, and Common Dreams (which is a news site). The same sites continue to load instantly on my old Windows 10 PC in Firefox, and on the new Windows 11 PC on Edge. Firefox is the only browser I use, I just use Edge to test sites, I uninstalled Chrome because of Google's privacy and AI issues.

In the lower left corner of the window for these three sites are the following messages, for the three respective sites:

• Waiting for www.paypalobjects.com...

• Sending request to jssdks.mparticle.com...

• Waiting for www.commondreams.org...

What's going on here? Seems strange that Firefox continues to behave normally on Windows 11 for all sites except these three, and works perfectly for these three sites on my Windows 10 PC. How can I further troubleshoot and fix this? I don't want to have to use Edge to visit these three sites, esp. Paypal and Venmo.

I'm guessing it has something to do with cache or history but am not sure how to proceed...

I have been trying for WEEKS NOW to sign into my bank! The bank can use a TEMPORARY password to access my account but once that's over, when I try to log into my bank I STILL CANNOT LOG IN!!!!!!!!!! WTF has happend to Firefox after that last "update" what ever it was they changed, made it IMPOSSIBLE for me to log into my BANK. The problem is NOT the bank it's FIREFOX & FIREFOX NEEDS TO FIX THIS CONNECTIVITY PROBLEM SOON IF NOT SOONER!

Dear friends,

For the last 10 days I'm facing problem to run google meet. Either I can't join or the app crashes right after joining the session. The app works fine on other browsers. Will appreciate your help.

With regards.

It is impossible to access a certain website using Firefox mobile. Edge, Chrome and safari work fine. I tried to turn protection off but it makes no difference. Why is this happening? Site is www.hlc.bike a large b2b distributor in the cycling world.

Been like this ever since I installed FF mobile.

This is only an issue in Firefox, so it's not an issue with my ISP or anything. Chrome shows my location correctly. Around 2 weeks ago after an update to firefox, it's just been constantly showing my location as Dublin. I'm in the UK. Certain sites show it correctly, some don't. Google doesn't show it right.

Several sites i check show it in the UK correctly, but google and a couple others show as in Dublin. I only run a limited number of extensions, Ublock surfshark, and bitwarden. If I put a uk location on surfshark, then google is right, but turning it off and then it is back to ireland.

When contacting my bank which I have been able to do for years I find that the login page of the bank opens and i put in the sign in details and send then nothing happens apart from the indicator just keeps on going round

Firefox worked this morning, but stopped in the afternoon. I ran an update, but could not connect to my gmail account anymore, or listen to the Radio France podcasts All this works from Google Chrome (not my default browser). All under the Mozilla VPN 2001:4860:7:150e::fc (why the IPv6 address?)

This is the reply I received from Protonmail: They say the latest version of Firefox caused the issue and is happening on other services as well. We have been using FF exclusively for decades and this is frustrating! Are you in fact working to resolve the issue on your end? Thank you.

Hello,

Thank you for your messages.

Please note that we are aware of this issue, and our developers are looking into providing a fix from our side. However, the latest version of the Firefox browser caused issue on many other services as well, so they are working on resolving it from their side as well.

I have provided your feedback to our development team. You can contact Firefox directly in order to escalate the issue further.

For the moment you can try using keyboard shortcuts such as CTR: + C and CTRL + V. We appreciate your understanding.

If you have any additional questions, feel free to contact us again. Kind regards,

Hello Mario,

I worked with Google AI for more than one hour troubleshooting this:

Opening a support ticket with Proton Mail Support is absolutely the best move. Since we proved that your clipboard works, your mouse works, and a fresh factory installation of Firefox still experiences the bug, the glitch is entirely on their end.

Proton Mail utilizes a heavily customized web text editor to encrypt messages. When their engineering team updates the background code for this text container, it can inadvertently break standard browser right-click paths—especially for Firefox users. [[1](https://www.reddit.com/r/ProtonMail/comments/p6j0tp/cant_copypaste_text_into_body_of_protonmail_email/), [2](https://www.packtpub.com/en-us/learning/tech-news/hackers-claim-to-have-compromised-protonmail-but-protonmail-calls-it-a-hoax-and-failed-extortion-attempt), [3](https://justinharter.com/an-actually-useful-review-of-proton-mail-vs-fastmail-vs-hey/), [4](https://www.reddit.com/r/ProtonMail/comments/p6j0tp/cant_copypaste_text_into_body_of_protonmail_email/)]

📑 What to Tell Proton Support To help their development team pinpoint and fix the bug faster, reply to your open support ticket with these technical details we uncovered:

- Specify the Browser: State clearly that you are running Firefox and that you just performed a full Firefox Profile Refresh (about:support), ruling out corrupt browser files. [[1](https://support.mozilla.org/en-US/questions/1234222)] - Detail the Extensions: Confirm you tested it with all extensions (including ESET and RoboForm) completely disabled, and the issue persisted. - Identify the Core Bug: Explain that the right-click "Paste" option is stripped only when clicking inside the Rich Text email composition body. [[1](https://proton.me/support/composer)] - Mention the Workaround: Note that Drag-and-Drop text injection works perfectly, meaning the editor container can receive data, but its custom context-menu script is failing to display the native "Paste" command. [[1](https://support.mozilla.org/en-US/questions/1234222)] They will likely log this as a known front-end interface bug and patch it in an upcoming web layout deployment. In the meantime, you can rely on the Drag-and-Drop trick or Ctrl + V to smoothly write your emails!

What can Firefox change so I can log into aarp.org or when I read an email open the article up from the AARP page. I continue to get error 15

Until a week or two ago, Amazon Prime Video worked without a problem on my Firefox browser. Now I cannot get Prime Video to open any show, nor can I access previous episodes of any show. I tried removing all my add-ons, including all my ad blockers and making Prime Video an exception to the enhanced Firefox browser feature. Nothing worked. Can someone at Firefox fix this problem or tell me why it happened? I CAN use prime video without difficulty on Safari and Chrome.

I installed a extension called MAL-Sync and tried to authenticate with one of my accounts. When I went onto the websites Simkl, MyAnimeList and AniList, I was not able to access some features. For Simkl none of the 'buttons' worked, disallowing me from logging in. MyAnimeList gives a "400 Bad Request." AniList says that it requires JavaScript. I checked to see that I have java script enabled, which I do since Firefox has it enabled by default. I checked my extensions and after disabling the only one that said disabled java script it still doesn't work. What do I do?

I can no longer access my local TrueNAS server nor router via Firefox. My current version is 133.0.3. Safari has no trouble. Firefox gives no warning, no Advanced button, no option to bypass security. All I get is: "Unable to connect An error occurred during a connection to 192.168.0.102.

   The site could be temporarily unavailable or too busy. Try again in a few moments.
   If you are unable to load any pages, check your computer’s network connection.
   If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the web."

I have tried so many settings, troubleshootings, workarounds, I can't begin to list them. It happens in troubleshooting mode. I have created SSL certificates on the server many different ways to no avail. I'm thinking I will have to abandon Firefox with it's obscure, no-way-through security. But I wanted to ask for help first. Please help.

When I search Google Images in Firefox, this pops up. I tried using an extension to hide it, but I can't see the rest of the image, which is inconvenient. Microsoft Edge and Google Chrome load it, so it's not an issue. Is this a Firefox feature? It's a hassle to disable the extension just to read the rest. Could you please give me some advice?

Youtube is pretty much unusable for me after the newest update. It loads fine the first time after I open or restart Firefox but after than it slow down to a crawl and it takes minutes for anything to load when I click on videos and menu buttons. It's not my internet since the website works fine in other browsers and it also works fine in private mode in Firefox for some reason. I tried clearing caches, permissions and anything related to youtube in my Firefox profile folder. I also tried creating a new profile and it does the same thing. The only way for it to work normally is using private mode.
