Firefox Support Forum

Every version of Firefox since 62.0.3 has been unstable on my system to the point of being completely useless. The crashes I suffer from were clearly introduced in the transition from 62.0.3 to 63.0, because every version from 63.0 to 70.0 has been unusable, and every time reverting to 62.0.3 gives me back a working browser. (By 'unusable' I mean crashing literally within a few seconds of starting up).

However, 62.x is now so ancient that if I can't have a working version of Firefox soon I will have to give it up in favour of something more modern and secure!

Please can you investigate and fix this issue!

Upgraded to Firefox 63.0 and all of a sudden started to see extreme sluggishness on every website I visited, especially Facebook, YouTube and some auction sites. I played around with the security settings, because this is what I saw changes in from my previous browser version to this new one, and that did not correct the sluggishness. I removed 63.0 and went back to my last browser 62.0.3 and bam, sluggishness gone. What changes were made that could have made this occur?

I have a web page that saves some data into local storage (localStorage.setItem). When I either close the tab or close the browser, the data is removed. When I use Chrome, the data is still there.

Is this normal behavior for FireFox? How can I have the data persist? Do I need to configure FireFox differently?

Thanks, -JT

Hi, How is it possible that this site can block my browser and that I have to go to the task manager and close Firefox? Can you tell me how I can block this site? I don't have a virus on my computer I use Avast and Malwarebyte Premium. Thank you for your help. Regards Michel

What used to be a great browser is now a real pain. I am running v62.0.3 on Windows 7 Pro and i7 CPU. Mostly consistent is the problem when I have 3 or more tabs open in which case FF becomes very slow or even unresponsive. I have tried uninstalling and re-installing which didn't help.

As I am developing a web application, having a good working Firefox is critical.

I have attached a Resourse Monitor capture for the CPU. If there is anything else I can provide, please let me know. Also please include a direct email address that I can respond to.

Thanks,

Ray

I'm having this issue in Firefox where it's rendering all of the Google fonts on two websites I've created as BOLD instead of THIN or REGULAR or whatever else they're set to in the CSS. I've found many instances online of users reporting this and similar issues over the past few years and have tried a number of solutions. Adding the following code as "extra CSS" to the Wordpress theme is the only thing that fixes it:

html { -moz-osx-font-smoothing: grayscale; -webkit-font-smoothing: antialiased; font-smoothing: antialiased; }

Yet adding this code has caused other rendering issues on the site. Both sites I'm having this issue on look fine in Chrome and Safari btw. I've troubleshooted by clearing my caches, disabling the few plugins I have installed and switched to different WP themes by different developers but the problem persists. I tried changing FF settings too... disabling plugins and add-ons, switched themes and turned off hardware acceleration to no avail. It should be noted I don't notice this on random sites I visit, just these that I've created using Wordpress. Checking another site I created by hand coding the Google fonts render fine.

Attached are two examples of the issue. First is the correct rendering, second is the incorrect BOLD rendering of the same text. Any thoughts anyone?

1. Needed to reinstall Win10 2. Did full backup, including C: drive 3. Reinstalled Win10 4. How do I find/reinstall my old bookmarks, which I assume are stored somewhere on the backed up C: drive

Thanks

Basically, if a PDF file has italics, they print out bold. If I print to a file and reopen it in firefox, it also appears bold and not italic on the screen.

I read a similar post where a user had the same issue, but their solution seemed to be "open in Adobe Reader," which seems like a lame solution.. Their complaint was that the extra step is annoying, and I agree. When I download a PDF file or open one from Firefox, I should be able to do so within the browser. I can do it chrome, but I prefer not to use chrome.

I tried to attach screen shots of the page as it is supposed to be and how it actually prints, but the "Uploaded images:" box just keeps spinning. If anyone can help and would like to see what my issue actually looks like, I can sent you a picture somehow, I'm sure.

My Menu Bar keeps vanishing in the last few iterations of Firefox 62. I'm not doing anything to cause this!

(And, yes, I know how to get it back -- but that doesn't diminish my aggravation of having to do so.)

http://www.spiegel.de/stil/seoul-fashion-week-street-style-fotograf-alex-finch-im-interview-a-1234757.html This page shows 10 consecutive pictures. To move from one to the other one takes too long. Have tried the same with Edge and that works fine.

I tried to download a 37GB game overnight and it almost worked but got stuck at 33GB. I got a message saying "failed" but I can continue the download. When I continue it goes on for some seconds and gets stuck again

Though YouTube videos play well, every 10-30 seconds or so, there's a frame or two where it goes back a quarter to half of a second. I've tried using the h246ify plugin addon, but it changed nothing. I see problems with video and audio playback are quite common in Firefox, but I haven't seen too many in Quantum (especially something so little as a random stutter). Any help is greatly appreciated, though it's not a very game-breaking problem (I've had this issue since Quantum came out and I installed Windows).

My bookmarks have all disapeared since firefox upgraded,i have tried all options but none work,i am aware of sync but it only retrieves the one's on my phone and when i restore them the next time i log on they are gone,HELP!

Of all browsers I have tried, only Firefox replaces 'style="height:164px;" with "style="height:0px;". '

The code is

<li style="padding: 0px 10px 10px 10px; margin-top: 25px;margin-bottom: 10px;position: relative;display: inline-block;"><img src="https://indelight.co.uk/wp-content/uploads/2018/09/photography_trans_full.png" style="height: 164px; width: auto; background-color: rgb(52, 226, 224);" ratio="4x4"></li>

However in Firefox this is replaced with

<li style="padding: 0px 10px 10px 10px; margin-top: 25px;margin-bottom: 10px;position: relative;display: inline-block;"><img src="https://indelight.co.uk/wp-content/uploads/2018/09/onlinesales_trans_full.png" style="height: 0px; width: auto; background-color: rgb(227, 114, 49);" ratio="4x4"></li>

This is not happening in other browsers.

Hi I'm using FF 62 on Ubuntu desktop 16.04 64bit when I download a file the button "Icon down" in the toolbar became blue. clicking on it open a list of downloaded files. clicking on a file on the list, not open the file with his related application. example: I download a pdf, then clicking on it open vscode !! If I open the download page from "history, bookmark etc" toolbar button and I click on a pdf file to open it, the file open in Document Viewer as expected. what I can do to fix ?

I have a pervasive problem where downloads of moderately sized files (> 100MB) are very slow in Firefox but fast in Chrome. When I begin downloads the speed is fine at around 4MB/s but it quickly drops down to < 200Kb/s. This happens across multiple websites and when on different WiFi networks. However when I attempt to download these same files using Google Chrome they maintain the initial 4MB/s download speed for the entire duration. I have already tried running Firefox in safe mode and resetting it using the "Refresh Firefox" help page. I am running Ubuntu 18.04.

This last update lost my passwords and most used websites. I tried contacting firefox but my login doesn't work. I went to my account and was signed in and changed my password for firefox and got the email saying I changed mt password and it still won't login for firefox support. I did the sync but no help.

the home content tab where "Top Sites" and "Highlights" appear, that part when i start Firefox has become slow to appear. first a loading icon would appear then seconds later the home content. at home, how i "fixed" this is to reset Firefox but at the office i do not want to reset as i'll loose many cookies/settings/etc.,

has anyone got a fix for this without resetting Firefox?
