Hello sdda,

You say: It work with another profile...

Try to restart Firefox with add-on disabled. Click the menu button menu , click Help and select Restart with Add-ons Disabled…. Firefox will start up with the Firefox Safe Mode dialog. Click start in Safe mode and retry. You see the comments? If it work means that the problems is caused by one extension Try to enable them one by one and isolate the problem Hope this help! Let me know how it work Have a good day!

Hi AnnaSycamore, since the poster uses Firefox 62 and you are running Waterfox with the pre-Quantum layout, you might want to create your screenshots in Firefox instead. If you don't want to disrupt your Waterfox installation, you can use a Portable edition:

Hi sdaa1953, when a site is known to work in Firefox, these are general suggestions to try when it stops working normally in your Firefox:

Double-check content blockers: Firefox's Tracking Protection feature and extensions that counter ads and tracking may break websites that weren't built to operate normally without the blocked components.

Do you see a shield icon toward the left end of the address bar, near the lock icon? More info on managing the Tracking Protection feature in this article: What happened to Tracking Protection?.

Extensions such as Adblock Plus, Blur, Disconnect, Ghostery, NoScript, Privacy Badger, uBlock Origin or uMatrix should provide toolbar buttons to manage blocked content in a page. There may or may not be a number on the icon indicating the number of blocked items; you may need to click the button to see what's going on and test whether you need to make an exception for this site.

Cache and Cookies: When you have a problem with one particular site, a good "first thing to try" is clearing your Firefox cache and deleting your saved cookies for the site.

(1) Clear Firefox's Cache

See: How to clear the Firefox cache

If you have a large hard drive, this might take a few minutes.

(2) Remove the site's cookies (save any pending work first). While viewing a page on the site, try either:

• right-click (on Mac Ctrl+click) a blank area of the page and choose View Page Info > Security > "Clear Cookies and Site Data"
• (menu bar) Tools > Page Info > Security > "Clear Cookies and Site Data"
• click the padlock or "i" icon in the address bar, then the ">" button, then More Information, and finally the "Clear Cookies and Site Data" button

In the dialog that opens, you will see one or more matches to the current address so you can remove the site's cookies individually without affecting other sites.

Then try reloading the page. Does that help?

Testing in Firefox's Safe Mode: (See the first reply.)

Thanks for the replies, I have found it was my quick launcher that was causing the problem. Strangely enough, re-enabling it after loading the website with it disabled seems to have cured the problem. I had previously tried disabling the plug ins but not extensions (my brain works in a strange way and didn't regard them as add ons - silly me). So thanks, all now appears well in the world.

Hello sdaa1953,

I'm glad that your problem is solved  !

I noticed that you marked your own post as Chosen Solution, but wouldn't you think that that mark should be on AnnaSycamore's post  ? After all, she's the one who suggested that one of your extensions might be the culprit ....

You can rectify the Chosen Solution mark by clicking on the "Undo" button to the right of that post and then mark AnnaSycamore's post as the one that solved your problem.

Totally up to you of course ......

I'm glad that my reply was helpful Thank you to all 3 for my First solution :) My first baby step and I fell excited :) To jscher2000,

I have five browsers installed of my machine but Mozilla Firefox is one of my favorite - never forget the historical battle between it and IE6. Today we have many alternatives, we used to ask for more; the today browsers are practically an entire system, a sui-generis OS. But at the beginning was Firefox. The main reason for using Waterfox also a Gecko based browser is that it is 64 bit application. The second reason are some extensions that I have used for many years that aren't compatible with Firefox Quantum. One of my favorite is Down Them All Another is FireFTP The latest versions don't work well with Firefox Quantum. But I use FF Quantum quite often especially at work and I appreciate it clean interface and it speed. Thank you again for your kind reply.
