Firefox 技術支援討論區

I can't stand Microsoft Edge. It's a CPU and memory hog. However, I must resort to using it when I watch a video from VUDU on any of my workstations. According to the fine folks at VUDU, Firefox is not supported in HDX or 1080i mode when using the VUDU site. According to the info that shows when you launch VUDU on a Windows device (in this case, Windows 10 or Windows 11) using Firefox, you get a message that the video is only supported in SD or 720 dpi mode. To get anything above SD mode, you have to use Microsoft Edge. Is there a developmental issue preventing such use or is this a limitation forced on Firefox users because Microsoft does want you using anything but Edge?

It's just a bit frustrated to have to use MS Edge instead of my default browser, Firefox. For the record, I just checked to be sure. There's a marked difference in resolution between Firefox and Edge on the same video.

Firefox recently upgraded on my desktop. I ONLY use Firefox - do not want Google, Edge, Etc. I can get into all of my on-line accounts with the exception of my Bank Account. I do not get a message about browser - but if I click SIGN-IN, it just sits there. I called my Bank...told me I have to use Google, Chrome or Edge - DO NOT WANT TO USE ANY OF THOSE. I had no issue signing in until it upgraded. PLEASE tell me how to fix this - I have cleared my Cache and History, etc. Nothing works. Please HELP!!! Do not want to use another browser to access this account - do not feel safe with any of them - why I use Firefox. Thank you.

I use Ajatix drop down menus in my website https://luresnreels.com. My .css and .js files in my website don't function apparently. The drop down menus do not work in Firefox, but do work in Chrome and Edge. Looks like it's not working on my iPhone also. I have a new desktop computer with Windows 11 home edition. Ajatix used to work fine on my old Windows 10 computer. What to do? Thanks

How do I tell Firefox what to do when I click on a link to a file (PDF, JPEG, Word, etc.). I want to have the options of either opening the file or saving it to a specific folder that I choose. I am 87 years old and somewhat computer-savvy, but please give me geezer-friendly instructions, step-by-step and click-by-click. Windows 10 and Firefox 101.

What happens now when I click on such a link is this: My only option is to save it -- and Firefox has chosen (apparently at random) a folder to save it to.

Whenever I go to fill out a specific form on a specific website for my job, when I load the page, the form is already filled out with a previous (and the same) form I had done last week. I have tried logging out of my Firefox account but that did not solve it. I have messed with every possible browser history, auto-fill, and saved addresses option possible. It is literally just this one form. I have no idea why it keeps pulling up one person's information and no one else. It's getting really annoying to have to go through and delete the information so I can put in new information. Using the forced reload command does not work wither. If anyone has any ideas as to how I can fix this, I would really appreciate it.

(My work computer runs Windows 10 if that is important to know).

I receive the following error message when attempting to login to the Keeper Password Manager extension. I have removed and re-added the extension with no change in results. I am using Firefox 101.0.1 and the latest version of the extension. Thanks for any assistance.

"A mutation operation was attempted on a database that did not allow mutations."

This website loads, but I'm unable to sign in to my account, nor can I see the details of the pages. It works fine when I open it in one of M'Soft's browsers, but I prefer Firefox!

I was having trouble with a website so went to Mozilla for help. Followed some of the instructions for removing cookies. Somehow ALL of my email folders have disappeared. Literally decades of saved emails. PLEASE HELP!

I have been using Firefox as my default browser for many years and much prefer it to the other browsers. However, several weeks ago Firefox started blocking the download of my morning newspaper. Now I have to copy the link from my morning newspaper email and paste it into Chrome to get access to my newspaper rather than simply clicking the link in the email. While I found this very annoying, when I couldn't find a workaround, I just continued to copy/paste into Chrome. Today I tried to download my IRA quarterly statement and found Firefox is blocking this pdf download also. Note that in neither case does Firefox tell me that they are blocking the downloads and they just do not download and some pdfs do download. So this is now getting beyond just annoying. Is there a workaround for this new Firefox problem or is my only alternative to define Chrome or Edge as my default browser and give up Firefox?

I am suddenly getting a number of web sites, which I have visited in the past and I know to be valid and secure, giving the Secure Connection Failed errors. Have you changed the programming behind Firefox which iis causing these problems. How am I supposed to get to the web sites with no ability to over ride the failure?

The red Tilde on my spell check in Facebook does not go away when the new correct word is chosen using Firefox., also the correct word is not displayed in the sentence until your push enter, it will then be corrected however before you push enter to post it, it will show it as the misspelled word. This issue is not prevalent on other browsers such as Chrome, Edge, Brave.

On certain (very few) web sites, I get a symbols font showing instead of text. For example on www.xe.com I have tried a refresh already, disabled addons etc..

Weirdly, THIS support form suffers from it so I am attaching pictures to illustrate the issue.

I have googled the usual stuff to no avail, so really stuck now...

many thanks for any pointers, Lozzy

I am getting the following errors due to vulnerabilities detected by Acronis Ceber protect:

Here is the warning I get when I look up more details from Acronis:
