When I go to the website https://www.rebateinternational.com/RebateInternational/contactUs.do and I try to fill out the webform on that page and use autofill to fill in the e-mail address, it gives me an error message that says "please enter a valid email address" even though the e-mail address is valid. Also, if I do not use autofill, but simply type everything in manually, it still gives me that same error message. This problem does not occur in Google Chrome, but it does occur in Firefox. Sometimes I can solve the problem by erasing part of the email address and then re-typing that part, but that doesn't always work. It also doesn't work if I erase the entire e-mail address and type it in manually. The problem does not appear to be caused by add-ons and does not appear to be caused by hardware acceleration, because I have disabled add-ons and have turned off hardware acceleration. It also does not appear to be caused by cache and cookies, because the same problem occurs after I clear the cache and cookies. I will appreciate any response you can provide to help solve this problem.

Lately I've had to reload/refresh pages more frequently because of download issues. In order to the in FF I need to press the F5 key. To do the same thing in either Edge or Chrome all I need to do is right click and a little popup screen shows me the reload/refresh right there. Much more convenient to use. FF should use a similar technique.

I have two computers. Both sign into the same Firefox account. Both instances of Firefox are the same version (134.0.1 64-bit).

On my main computer, creating a new tab is set to Firefox Home (default), and clicking the "+" sign to create a new tab results in the recommendations appearing as seen in the first image (firefox_2025-01-19_17-42-57.png)

On the other computer, creating a new tab is set to Firefox Home (default), and clicking the "+" sign to create a new tab results in the recommendations appearing as seen in the second image (firefox_2025-01-19_17-43-57.png)

How to I get both instances of Firefox to do the same thing when creating a new tab, i.e. organize the recommendations like the second image?

Recently when I try to download a file Firefox seems to give it a random amount of time before it attempts to open the file. For small files this isn't a problem, as it always seems to give at least a few seconds, but larger files get cut off. This leaves the file corrupted/incomplete.

I have no idea why is started doing this. Just one day it started opening everything I downloaded, be it PDF, image etc when complete. I turned this off and it has stopped for things that download properly, but it's still doing this 'cut off' attempt to open.

Any help would be appreciated, thanks,

When a tab is opened or moved into a new window (image 2.png), the additional windows will disappear from the Windows taskbar after a few moments (image 3.png) and cannot be accessed via Alt+Tab, the only way to reach that window is via dragging the windows around or with the Firefox View tab.

When I open Robert Reich's substack article of the day, I'm finding that whenever the comments, the word "Trump" is replaced by "Mr. Bully". One can see the original by opening repost. If it is one of my own comments I can open Edit and see the original. I asked Substack support about it and they say it isn't them and to check with my browser. OK, Firefox, is this a new "feature" of Firefox or someone hacking Firefox. Would you please look into this for me.

Hi there, I just got a new work laptop and tried to sync my firefox browsers so I could keep my passwords and bookmarks from my old laptop. Unfortunately I forgot my password, so I had to reset it on my new device. I logged in again on my old laptop but it's still not syncing or updating the bookmarks on the new laptop. Is there any way to move my bookmarks and passwords over to my new laptop? Thanks!

This is an exact copy of a question with the same title by Steve Ediger, of August 2022, now archived.

Firefox has my credit card information and it shows up in a window when I go to pay for something, but when I click on the credit card I want to pay with, the details appear on the form but get removed almost instantly.

I am in UK. It was working until recently.

None of the earlier answers have helped.

A video of what is happening . This only happens when I search something up, for example, if I search more than one thing up on Pinterest, Google and sometimes Youtube . . . I'm sure it's not related to any extensions, the only one I installed recently was Privacy Possum, but after noticing this issue I deleted it and it didn't resolve the issue.

Help me Please it's Killing my Eyes

I'm on Developer Edition of Firefox. In previous versions of Firefox (Probably 132), I could share the window just fine, but since an update to either Teams or Firefox, it just results in a blank screen for viewers.

Is there any addon or feature within addons management icon (from toolbar) to Disable Extensions and Apps in one-click like Chrome has via this addon?

I just created an account to sync my passwords and bookmarks from an old Macbook to a new one. I can see both devices on the Mozilla account but the Sync does not work. Nothing appears in my bookmarks.

thank you for your help.

Have a new modem/router (Assis G34). Only getting 57.2 mps download and 9.6 mps upload. In trying to go to a website, it times out.

Tried Microsoft Edge. It worked OK when I wasn't using Firefox at the same time.

Planning to get a range extender. Is that the solution?
