How to debug a web application running on Opera on iPhone? - iphone

My web application has an issue. It breaks while running on Opera + iPhone. How to debug such combination?
I've looked into many online posts and posts that are similar to mine,
but those posts are either inaccurate or outdated, like
How to debug on Opera Mini?
It is easy to reproduce the bug. I am sure i can address the issue if I can observe what happened to the application during the process.
It is a really a margin case. I would be lucky and happy is someone had dealt with it before.

Disable Cache in Chrome Developer Tools Not Working

The "Disable Cache" option in Chrome Developer Tools stopped working about a week ago (Mid February 2021).
Is anyone else having this problem and is there a fix for it? I mean a browser fix. I already know how to "Trick" a browser into reloading resources, but Disable Cache was working fine until recently and is the simplest, preferred solution.
I can't recall having changed anything browser or network related. It just suddenly stopped working.
Maybe you have a general problem with cache control. You can see my answer https://stackoverflow.com/a/67366558/4489551, and I hope it will help you.

Does Firebreath 1.6 support Internet Explorer 10?

Does anybody know if there are some basic problems using a firebreath-built plugin on IE10?
A plugin that I built using FB 1.6 that works fine on IE9 on Windows 7, no longer works on IE10 on Windows 8 classic desktop. I suspect some issue with the ActiveX interface. I installed Chrome on Win8 classic and the plugin works OK on that browser.
Admittedly, I don't have many debugging details yet. But I wanted to see if there were any general issues I should be aware of before diving through the FB code.
Thanks very much.
Bob
There are no fundamental incompatibilities that I'm aware of, however our plugin does seem to have some drawing issues in IE10 that I haven't had the luxury of tracking down yet.
If you could be more specific about what "no longer works" means it might be easier to give you some advice.
Does it fail to load? Fail to talk to javascript? Fail to draw (like ours)? Crash the browser? Curdle your milk and demagnetize your credit cards? Sing Beatles songs out of tune?
Without some indication of what exactly is going wrong it's hard to know what to tell you.

Facebook like button doesn't show in Chrome

I added a Facebook like button to my site, which was generated by the Facebook tool
http://developers.facebook.com/docs/reference/plugins/like/
it works perfectly in FF and IE
But doesn't want to work in Chrome 9
Does anybody know why it happens this way ?
Sorry guys, it was really stupid of me.
The cause of this mess is a Facebook Disconnect extension I enabled a few weeks ago - https://chrome.google.com/webstore/detail/ejpepffjfmamnambagiibghpglaidiec
Since it works for you I started exploring my own Chrome.
Thanks for your support, you helped me to understand the issue.
FYI - for anyone that finds this, Avast is blocking social media sites by default now with their web plug in! Grrr...

Why might cache-manifest fail to get mobile Safari to cache site while working as expected on desktop?

I'm playing around with a simple web app locally, and can't quite figure out why it is not caching correctly on the iPhone. I am serving a .manifest file with the correct MIME-type, and the site works perfectly fine with my local server turned on or off on desktop Safari, Chrome and Firefox. It is only mobile Safari that is failing to cache the site. Any ideas why this might be?
It seems to be an iOS bug.
I found out that mobile safari will always run into an application caching error if you have at least one web view opened and the you clear the browser cache. I think that clearing the browser cache will destroy the cache database. All accesses to the cache database will then fail. It seems that the browser creates this database only on startup.
To get the application cache working again close all safari views and finally close the browser by returning to the home screen. Now applicaton caching should working. Some mobile devices also requires switching on and off.
If you know a methode to detect this situation let me know it, please.
I had a similar issue but Safari and iPhone were both NOT working whilst IE and Firefox were working. The reason was complex. One was a misspelling of the word "manifest" in the HTML tag. Silly mistake and very frustrating that IE and FF still worked offline. The other issue was that I was using default.asp as the main page of my app and not including this in the manifest.
My app was mydomain.com/myapp/ and thus the browser never saw the "default.asp". Also, according to the HTML5 spec, the main page need not be in the manifest but apparently Safari sees that a little differently...
I can confirm that the bug is also present on iPAD running iOS 4.3.
I spent quite some time to make the offline application cache work on iPad. I can confirm that the workaround mentioned in the previous post works.

Website Causes Mobile Safari Crash (Replicable)

For some reason http://shirazraqs.com is causing mobile Safari to crash. I've never seen anything like it and it's 100% replicatable so it's a bug on the site.
I've already tried ripping out all of the javascript but the bug persists even then.
Any other troubleshooting advice? Better yet, has anyone heard of this? I've been unable to find anyone experiencing similar problems via Google search :(
It turned out to be an issue with the new Google Fonts API. Removing the Google Fonts CSS Stylesheet got rid of the problem... Head's up Google!
