Firefox Support Forum

This seems to happen on an annoyingly frequent basis. Since restarting my Windows 10 PC Firefox has decided to ignore the settings and scrolling the mousewheel causes it to go back/forward in the history rather than down the page.

I've noted there are questions/solutions to this going back to 2007. None solve my issues with it.

middlemouse.contentLoadURL is false mousewheel.default.action is set to 1

Any advice would be greatfully recieved.

Printing is damaged. All margins are set to zero. When you look at the print preview, you can see that the width of the document must be smaller and the height must be larger. With the red boxes, I made sure that it was A4. It is displayed correctly in other browsers, but not in Firefox. See the screenshot. What can I do?

Dear mozilla community,

I cannot get firefox to start, and I need help to troubleshoot this. What I already did:

• remove and reinstall (apt)
• rename ~/.mozilla to trigger recreation
• start using the command line
• start in safe mode

The only symptoms are <defunct> processes (see screenshot).

I need more information to find out what went wrong. Where can I find this?

Details

• apt
• firefox_78.0+build2-0ubuntu0.16.04.1~mt1_amd64.deb
• Linux Mint 18.3 Sylvia

Say that I have a login at a site, and I got there previously with another browser. When I go to the same site with Firefox for the first time, that site's ID field might drop down to show a number of entries, and many times (but not always) there is no "View Saved Logins" below the list.

Here is an example of a site than many readers of this might not go to: DevonTechnologies.com and this might be the same for you. Devon's login ID wants an email address, and the field dropped down to show 29. A bunch of them were emails I would swear on my kid's heads I have never used anywhere, not even in another browser, and one was a misspelling of my own email address. Only a small few were addresses that were valid elsewhere. But here is the rub: A search of about:logins for the weird addresses and my misspelling came up empty.

Further, I can go to another site I have never visited with Firefox, and I might not get a drop-down at all or I might get just one of my three typical email addresses.

For those sites where I have used Firefox for the first time, the questions are

• Where did Firefox get those spurious addresses?
• Where did Firefox get a good address, and why did it leave out the "usual" others?
• Why are the odd logins not found at about:logins?

I have Firefox 76.0.1 under Catalina 10.15.4, and I sync with Lockwise.

Thanks.

When I try to attach a file to an email send in Gmail, nothing happens. The upload bar shows no progress and the email sits in the draft folder. The size of the file has no bearing on the problem. I've tried running in Safe Mode and even did a clean reinstall but it didn't help. The problem does not occur with the same accounts in Chrome or Opera; only in Firefox. I've tried everything recommended here, but nothing helped.

For example, same webpage, vivaldi using only under 10% of GPU, FX would pump voltage constantly and using crazy 60~80%....causing unnecessary heat and power consumption, restart with safe mode only improve this issue but can't solve it,gpu still pump voltage and jump twteen 0%~30% usage and manually disable all my add-ons not helping. Does anyone notice same problem?

Where do I go to suggest new features? This seems to not be the right place, but it doe seem to be the correct place to ask where the correct place is.

Please Note: I Write and modify Plugins alot. This is not about plugins/extentions or dealing things plugins can do. This is about FireFox it self.

Soemtimes, when I open Firefox (77.0.1), or do a search, a microsoft edge popup occurs. Attached are two screenshots showing it. I have checked everything under permissions. I even went into IE 11 and set to highest security and popups. Still the popup rears its ugly head. I appreciate any advise. Thanks.

This problem is not new. Every time I've gotten fed up with Chrome and have fled to Firefox I've had this problem... I'm talking years! Screenshots are attached.

If I just open Gmail, fonts display correctly in my inbox. If I click on an email to open a website, or type something into a Google search, I get what's attached. I have none of these problems using Chrome, Safari, or doing a Yahoo search.

I don't know if it's a font conflict? I've cleared the cache and cookies and restarted. I've opened Firefox in Safe Mode... the issue persists. Our Mac Book Pro laptop using Firefox as the browser also does not have any issues.

I hope someone has some experience with this so I can FINALLY fix this. Thanks to anyone who can help!

bold text Firefox is now opening new tabs for the same URL. How do I make it stop? I thought it started when I added honey. So I deleted that add on. No effect. Is this some new normal? Is there an add on or something to make this stop?

For some reason I cannot see comments on the website for Refinery 29 anymore. This started a couple months ago. I can see it if I use Edge. I have tried numerous things, disabling the tracking, disabling the adblocker, deleting cookies for the website. Any suggestions?

Bonjour Lorsque j'essaie de me connecter à ma banque, j'entre le n° client et je ne peux pas entrer mon mot de passe.

FF 77.0.1 W10.

I get this message on one specific website, every time I visit. It happens on other pages, but not continually, and not regularly.

Is there a remedy? Updated recently and do not want to have to reset or do anything drastic.

Asked this two other times, but I tagged on to previous conversations. Unfortunately, I did not get the usual prompt response.

Thank you.

Yahoo has hijacked all search engines on Firefox and none of the solutions offered work. I have set Google in my preferences, followed all the steps etc. Even bookmarked Google search -- still get hijacked. What to do aside from abandon Firefox (preferred) to Chrome (supported by my institution, reliable, but - Google)

Video plays fine, from sites I visit, like YouTube and Vimeo, while using Firefox. But I moved from my home town some years back, and I fortunately found out, that the Funeral Home there, offered email alerts when someone passed away. Some alerts, had special Memorial Video's of the deceased along with their family. It's very nice that as we age, occasional Obituaries would bring back special memories to some of us. I switched to Firefox some time back, as I was tired of dealing with Chrome all the time, and this is what I discovered: In Chrome and Firefox both, the email alerts are based in HTTPS:, and are of the MP4 video format. They play just great, in Chrome, but in Firefox, the area inside an Obituary Alert, where the video is located, ONLY HAS A BIG BLANK SPACE, that shows nothing at all. The MP4 Video, is not present. This Obituary, is what I am speaking of - https://www.vincentfuneralhome.net/obituary/john-herpin-sr, who is the father of a friend I graduated with. Towards the bottom, right after the name Marguerite Herpin and before Sign Guestbook, is a big blank space, where the video is shown to exist, in Chrome. Is there a setting I need to change or make something else happen, so that I can start seeing the MP4 video, is there to be played? Thank you in advance.

I give up. Ever since the 77.0.1 update nothing seems to want to load without a lot of work on my part. Gmail doesn't load more than half the time. Weird things happen on the screen occasionally and some photos don't load properly. I've tried all the suggested fixes. I'm using other browsers until this is fixed.
