Make sure you are not blocking content.

Start Firefox in Safe Mode {web link}

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?

Thanks Fred but the problem persists in safe mode.

Hello turiyaa,

The web console shows :

"cross-origin request blocked (reason cors request did not succeed)"

See : CORS request did not succeed

Maybe take a look at this :

https://stackoverflow.com/questions/24371734/firefox-cross-origin-request-blocked-despite-headers/31015385

Thanks McCoy, but all this means nothing to me. My computing knowledge is very limited.

Im not getting any error messages and nothing is being blocked. Pages are opening and I can read and scroll. I could live with it if it wasnt for the text jumping 2 to 3 cm up or down every few seconds.

When you're on that site; would you open the web console (Ctrl+Shift+K) and see if you get the same message that I do ?

Assuming that the web console gives you the same message as me; would you try this please :

Type in the address bar about:config and press Enter (ignore the warning)

Type in the search bar and look for the preference :

security.certerrors.permanentOverride

and set its value to false

Then close and restart Firefox.

If that doesn't make a diifference, reset the value.

Thank you for posting what the web console shows - in all honesty : I haven't a clue what that's about, but I am sure that another contributor will come to your rescue.

FWIW : when I go to https://www.thaivisa.com it loads without any problem (was told to turn off my adblocker), and of all the tabs there are only two that never finishes loading, among which the Forums tab .....

Thanks for trying to help.

This also appears with contr-shift-k before it settles into what I posted before. Dont know if u can make any sense of this:

Im in Thailand so goodnight its bedtime now. Hopefully this can be resolved tomorrow.

I always suspect competitors, i.e., google, of causing stuff like this to get u to return to using Chrome.

Well, it's "tomorrow" and today the forum page loads just fine (for me, anyway).

Have you tried it yet ?

I did inform thaivisa.com and they just replied "Technical support have investigated the issue and it appears it may now be resolved. If the problem persists, please let us know." But I just tried it again and the problem persists.

I just tried the site again; when I use the link you posted in your first post : loads immediately. Then I tried thaivisa.com and clicked on the forums tab and no problem.

When you contact Technical support again; will you keep us posted please ?

I totally forgot to ask :

Have you turned off Enhanced Tracking Protection on that site ?

Yes but it made no difference so I have turned it back on again.

Yes I will let u know of developments with thaivisa.com's technical dept.
