Diễn đàn hỗ trợ Firefox

Since updating to last version, when trying to access my two banking accounts, on different banks, the send button, when entering my user and password, doesn't do anyting. All other buttons and links respond.

The scrollbar slider isn't displaying correctly. If I grab the screen, zoom in, and look very carefully, it is possible to see that the slider is a very slightly different darker shade of grey to the rest of the scrollbar, but it's almost impossible to see, so something is clearly not working properly here. The scrollbar should be highly visible as it's the most often-clicked control of the entire browser.

Saved a new password for a site in the manager, but the update on the site failed. Now I can't login there (need to change the email address linked on the site, and can't without the old password that I forgot)... and the support on the site is bad.

Hello, I run a movie and drama-related website: https://tvmon.com.co/. Recently, I’ve noticed that Firefox occasionally throws the following error when trying to access the site:

"Secure Connection Failed An error occurred during a connection to tvmon.com.co. . The OCSP response contains an invalid signing certificate. Error code: SEC_ERROR_OCSP_INVALID_SIGNING_CERT"

This issue is very strange because:

1. The site loads fine in Chrome, Edge, and Safari.

1. My SSL/TLS certificate is valid, up-to-date, and passes external tests (SSL Labs, etc.).

1. The error only appears occasionally in Firefox, refreshing sometimes fixes it, sometimes not.

1. Hosting and server logs show no issues at all.

I suspect this is related to Firefox’s stricter OCSP validation, but I’m not sure how to debug or resolve it. Since my site streams drama and movie content, this error is frustrating for users who rely on Firefox.

Has anyone else experienced this intermittent OCSP signing certificate error? Is there a known fix or workaround for Firefox-specific validation issues?

I would like to have a solution to reactivate all the bookmarks in the personal bar.

Hi. I'm in Windows 10 Extension using latest version of Firefox 145.0.2.

Every time I try to log into my Gmail account, a Windows Security Pop up says: "Making sure it's you. Please sign in to google.com. This request is coming from Firefox, published by Mozilla Corporation."

I'm already trying to log into gmail using my user name and password! I cancel out of the pop up and then it takes several tries to finally log in to gmail.

Is there any way to disable this pop up request at Firefox's end?

Thank you. JHL

So I reformatted my hard drive and everytime I finish I reinstall Firefox. I have an account where I log in and it put me back where I left off with all my past bookmarks that I saved. Ive been doing this for 10 years but today not sure whats going on but when I logged if all my stuff has disappeared. Please help or contact Mozilla regarding this. I cant understand why one cant directly speak to the ones who developed this browser. Quite frustrating

Hi i accidentally adjusted the width of the sidebar too far and now i cant pull it back over. I have tried using the show sidebar button but nothing happens. is there a way to reset the width of the sidebar without having to drag it?

if i search something on firefox the search bar doesnt show english and after clicking enter for the answer sometimes it doesnt come in english. i have chosen english as the only language but sometimes i get results in bangla too. i want my results to be in english only.

Had to recently reset my browser and lost all my history. Apparently it messed up my custom settings in some way as well.

New Tab still shows my FF homepage with shortcuts and history gone - I've managed to get those back but with one huge problem:

- Clicking on a shortcut opens it in the same tab, whereas earlier I had it working when clicking on a shortcut would open it IN A NEW TAB.

Where's the setting in about:config to fix this???

If this feature has been removed - why???

I cannot complete an online payment from a checking account on firefox. I get to the point where it says submit payment and it always kicks me back to the same screen. I have to change browsers to complete the payment. Is there a setting that is preventing me from completing the payment?

I can't delete history. I know how to do it (ie menu, click "clear recent history" etc etc) but it just doesn't do it. I've uninstalled Firefox and taken the option to "refresh" instead of reinstall. Didn't work. Uninstalled it again. In the reinstallation I asked that it NOT import my settings etc but it did it anyway. Back came Firefox, complete with my history! I just can't get a fresh start. With regret, I'm starting to use a different browser. I dislike doing that but at present I have no choice. Whenever I use Firefox, I just clutter up the place and can't get rid of history.
