Diễn đàn hỗ trợ Firefox

Sometime after around Feb 13th, I think I might have rebooted for a Windows update and now Firefox pages completely lock up until the entire page loads.

To be more specific, I can still switch tabs, open menus, etc... but I cannot interact with anything on the page itself like click links, type in text fields, right click to get the context menu... but if I switch to another tab, I can interact with that page just fine. In addition, while the page is frozen like that, I can't use the back button either, but clicking it (or using the back button on my mouse) will make the browser go back only after the page fully loads.

Why is this bad? Some pages can take 10 to 20 seconds or even more to load! So even though I can see the link I want to go to almost immediately, I have to wait until every picture is done loading before I can click it.

In addition, things like the dropdown you get on google as you type in the search box will freeze the page when you select them. For example, I go to google, I type "Firef" then click the Firefox autocomplete. The entire page freezes for a couple of seconds before the screen is cleared and goes white and then it starts loading the next page.

Other things I've noticed, those google captcha things where you click the checkbox for "I am not a robot"; those can take over 15 seconds to load and freeze up the page PLUS clicking the checkbox ALSO freezes the page again for another 15 seconds.

This happens in safe mode too and with all addons disabled.

Hi, I'm having a problem with my Firefox loading major websites like Gmail, Facebook etc.. The loading time of these just went terribly slow... And when a webpage like these is finally displayed, it still keeps loading for a very long time, and navigation the page itself is very laggy. For example, if I type in a simple search query for a Google-search in my URL-Bar, when I hit Enter it takes more than 7 seconds until the results are displayed..! And even after that, the page is still loading for a few seconds. Strangely it works fine in other browsers.

I already tried the following approaches: - Reinstalling Firefox and deleting all Mozilla-related content in AppData - Using Firefox in Safe Mode with diabled add-ons - Disabling and Enabling the hardware acceleration - Disabling and Enabling access for accessiblilty services

After reinstalling and restoring my basic browsing data through Sync it works fine, until I start Firefox for the second time. It's the first time I encounter a problem like this. Any ideas?

Last night after using Firefox for years I started experiencing extremely slow response time on most sites. Kept getting a message "A web page is slowing down your browser. What would you like to do?" The sites work fine on Internet Explorer. So I know it is an issue with Firefox.

I tried so many things and has been very frustrating. After uninstalling and reinstalling several times and trying various things I believe I was able to troubleshoot possible cause but don't know why it is happening. If I reinstall and bring up Firefox the pages work fine. For many years I have been using Profile Manager option of Firefox to run multiple sessions. Now after setting up a profile, if I open the profile session this is when the slowness occurs. This has never happened in the past, never!! I could run 1 session or multiple and never had an issue. Now if I run one or more sessions I get the slowness and no response from many sites, which are working fine on other browsers.

PLEASE HELP!!!!

Hi, Since version 58.0.2 (64 bits) of Firefox under Windows 10, the profiles I open via the profile manager ("...\firefox.exe" -no-remote -p) are very slow to load web pages. Not every pages appear to be affected, but all Google services for example are very long to open, showing the message "A web page is slowing down your browser, what do you want to do, wait or stop it". On the other side, when open without the profile manager (this time via "...\firefox.exe"), each profile works normally : the loading speed of the web pages is correct.

I tried to create desktop shortcuts to each profile as a work around, but this opens a second instance of the already open profile and not the one targeted by the shortcut (zumaxb described the same problem here : https://support.mozilla.org/fr/questions/1205523#question-reply ).

Thanks for your help.
