Forum Firefox zajednice

Hi everyone,

I run a construction estimating website where we share project-based cost estimates and detailed breakdown for contractors, architects

I’ve noticed a weird issue in Firefox lately.

Some of the heavier pages (especially ones with large tables, detailed breakdowns, and embedded content) start getting really slow or sometimes even become unresponsive in Firefox. The same pages load completely fine and smooth in Chrome, so I’m trying to understand what Firefox might be struggling with specifically.

I already tried the basic stuff like clearing cache, testing in private mode, and disabling extensions, but the issue still keeps coming back.

It seems more noticeable on pages with a lot of structured data and embedded elements, so I’m wondering if it could be a rendering, memory, or layout issue on Firefox’s side.

Has anyone dealt with similar performance issues on Firefox with data-heavy or content-heavy web pages?

What should I look into next: layout structure, CSS rendering, JS execution, or something Firefox-specific I might be missing?

Any guidance or debugging tips would be really appreciated!!

A client of ours has recently raised an issue with with us stating where right-click, Paste does not work when adding text to a new LinkedIn post

After investigating, we have been able to reproduce the same behavior on our devices.

However, from our testing, we can right click to past on comments, messages and searches just fine

Troubleshooting already attempted:

Cleared Firefox cache Performed Firefox refresh Tested across multiple devices

We have confirmed this occurs on:

This issue appears to have started after updating to Firefox version 151.0.0. I know this as i have tested this on my work laptop, appeared to work fine then stopped working after manually updating from 150.0.3 to 151.0.0.

Please let us know if there are any known issues, additional troubleshooting steps, or if further diagnostic information would help I have attached screenshots of the issue.

I have also tested this in the Google Chrome web browser and appears to be working correctly as also seen in the screenshots.

With Duckduckgo set as search engine, if I type a search or go directly to duckduckgo search page the current tab crashes and the "Tab crash reporter" is displayed.

Google, Bing, etc work.

I have Duckduck privacy protections, privacy badger, and ublock origin all disabled for duckduckgo.

For 24 hours now I have not been able to connect to Facebook via Firefox browser on my laptop at all. I can connect on my phone, but not my laptop. I've made sure there are no extensions on my browser, my firewall is off, all cookies and cache have been cleared, I even Uninstaller Firefox and reinstalled it. When I try to bring up Facebook, nothing happens. It won't even bring the page up. All other websites work fine. I can't even bring up Facebook to clear the caches in Facebook per the troubleshooting guide. It says to open Dacwbook and click the lock on the address bar, but I can't even open Facebook. What am I missing here?

Hello all

 Firstly I have been using Firefox for about 2 decades and it has always worked perfectly - you can take a bow.
Now for my problem
I have been using Firefox for internet banking for many years without any problems - the usual login, password ans secret questions. Just after Xmas my bank updated it's website and suddenly nothing works. I was told that it now only works on Chrome and NOTHING else - not Firefox, Edge or anything else. I am able to log-in but can't see my account balances or perform any other functions - it just jams up to the point that I even have trouble closing Firefox.
I use Firefox exclusively because I don't trust Chrome or Google - they are just a massive data collection/sharing operation. I have Chrome Mask installed but it just doesn't make any difference.

 Is there anything that I can do or add-on to over-ride this problem?

I am running Mint Linux 22.2 with Firefox 151.0.1

I recently switched to Mozilla Firefox and noticed that one of my business websites won't open in the browser. I'm not sure whether the issue is with my website or Firefox itself. Has anyone experienced something similar?

Greetings,

For the past three days (A/O 06/01/2026) I, (and others who have posted on various sites) cannot access a functioning log-in page for Google or Gmail via Firefox. If I (and others) use an alternate browser e.g., Edge, the log-in page functions and displays as it should. However, when using Firefox, the page displays as the image I've included - no functional 'log-in' icon and no Username or Password box. Using 'Private Viewing' makes no difference. As other browsers work, I will assume this is a Firefox issue. As there is no way to submit trouble tickets, I'll leave this here in hopes that someone from Firefox will pursue the issue.

Thank you in advance for any information or resolution.

With Mozilla Firefox for Linux Mint 150.0 after logging into Chase Bank , when trying to pay off my credit card, I get a message: "It looks like this part of our site is not working right now". However the site works perfectly with Chrome, thus the problem must be with Firefox. I have cleared the Chase cookies and still getting the same result.

I used to be able to log into Peacock without issues. Either Firefox changed something or Peacock did. But it no longer works correctly. I can sign in, but the main menu appears for a split second, then the screen goes black.

When contacting my bank which I have been able to do for years I find that the login page of the bank opens and i put in the sign in details and send then nothing happens apart from the indicator just keeps on going round

Hello, https://www.so.energy/myaccount/usage shows a vertical bar chart representing electricity usage over time. If I hover the mouse pointer over one of the bars in the Edge browser I see a pop up that gives details of the electricity use represented by the bar. If I do the same in Firefox the bar changes colour to indicate it has been selected but there is no pop up. Is there likely to be a Firefox setting that is preventing the pop ups from showing? Alan.

When I try to attach file via drag & drop, the Firefox always display "Download file" as attachment. I don't know why because it properly worked before. but after some updates, drag & drop is not working.

The version of Jira at my office is not changed for years(v8.12.1#812002-sha1:7c28d59) and drag & drop is working via Chrome, Edge and etc.

Hello,

For few days, it's impossible to connect to FACEBOOK. I have the latest version of FIREFOX, but I have to use another web browser (EDGE) to connect to FACEBOOK. The problem is the same with my two computers with the latest WINDOWS.

Thank you for your help to solve my problem

Google has added some AI 'ads' to their title page? This just appeared a day or so ago on my system. How did I remove it, block it? Attached is an image of what I am asking about. What is interesting is in Chrome I can explicitly turn this junk off. But when using the Google search title page with Firefox, there appears to absolutely no way to disable it... very nasty way of forcing you to use Chrome?
