Firefox Support Forum

I don't know if it is the last update, but since this week the scrolling menu on numerous website on firefox become messed up and instead having their usual limited height (like no more than 400px) when there are numerous links in the menu, they now reach the bottom of the windows.

I added some image to explain the problem with two sites: one screenshot show firefox bug, and the other is a screenshot (from edge) to show how the scrolling menu with limited height was supposed to be before the bug.

Also the problem appear even in the debug mode, so i doubt it is an extension trouble. How to solve this problem?

these last days, whenever i visits any page that fall under archiveofourown.org, i often end up with the page just trying to connect for ages, only to give up and say "secure connection" failed. and that " the authentication of the data could not be confirmed" (i don´t get an error code) sometimes it works, sometimes not. i can reach the pages fine on my phone, and on other browsers. i can also connect to other webpages so it´s not my connection that´s the issue. i use the page a lot, so this is really an issue. i recently switched over to firefox, and i don´t wanna have to switch back.

A couple of weeks ago, a message came from Firefox saying - do I want the facility of opening a Firefox window on starting it? I thought that would be a confirmation of my existing setting of opening Firefox with the previous tabs. But no. Firefox now opens a separate blank window in addition to the previous window with the tabs.

How can I stop the opening of an additional blank window, which I now have to delete everytime? Thank you

Hi how do I i prevent Firefox from going into efficiency mode. When Firefox goes into efficiency mode it be comes slow and unresponsive. if I manually uncheck efficiency mode in task manager Firefox becomes quicker and less laggy until a few seconds to minutes later it goes back into it. The performance of Firefox in efficiency mode makes it almost unusable and can take up to a minute for it to start working again.

Firefox keeps crashing randomly, sometimes at startup, and sometimes just in the middle of a session. Sometimes just one tab will crash, and other times it'll be the entire browser. I ran it in troubleshoot mode and it still crashed, so it's not caused by an extension or anything. It never used to do this before and I don't understand what's causing this issue.

Wishing to view my own html file in my Ubuntu Linux system I pressed the Alt key which I thought would give me a "File" menu. I could not see one. How do I get it?

See attached screen grab of error message.

We use primarily Thunderbird and Firefox (latest versions). Everything works normally except a site from Constant Contact (that tracks when a customer/client opens or clicks on an email. We normally use uBlock and the problem occurs with and without that extension installed. I'm stumped. Thanks for any helpful you can provide.

As of today every time I open a FF window it has a sidebar for history. I do not store history and need to stop this. I do not want to close it i want to disable this annoying new function or I need to delete FF and choose a different browser.

Hi Team

I am fan of Mozilla and use ist now for years. I installed the add ons but dont know really what I need to do when content on the site is not displayed. How do I know what I need to deactivate, set or change to see the content? Do you have any trainings or explanatory maerial/links?

Thanks Aylin

I play a game at Vegas World. It's basically a free online slot machine site. I have played it for years with Chrome. Recently switched to Firefox. Playing an auto spin slot game, Firefox gets slow and hangs after about 25 spins. Chrome will go for 10,000 spins. So, Firefox is useless on game sites. I don't really expect a fix or solution. And I don't actually expect to use Firefox by the end of the day.

I maintain a website that I update on a regular basis. For the past month, none of the updates have shown up in Firefox. I've refreshed the page, cleared the cache, logged out and logged back in. Nothing has helped. With other browsers, there's no problem -- Chrome, Opera and Safari all show the website updates as soon as I post them. I'm using Firefox 122.0.1 (64-bit) on MacOS Sonoma 14.2.1 (MacBook Pro 14-inch 2023). The website uses WordPress, hosted by DreamHost. I have two other WordPress websites, both hosted by WordPress, and Firefox is showing updates with no problem. I'm querying DreamHost on this as well, but I suspect they'll must say it's a Firefox problem.

I am trying to use an input type of month but it is not rendering or behaving properly when viewed in the latest browser version.

The example from Mozilla tech site is below and when viewed in Firefox it does not work either. <input type="month" id="start" name="start" />

Is this no longer supported by Firefox?
