Can’t open Opera all of a sudden

I’ve been running Opera on one of my machines for about a year without any issues.

When turning on my laptop this morning and try to open Opera I get the error message.

Can’t open user profile directory, because you lack sufficient privileges. You might want to contact the administrator of this machine.

I did run a software update the night before and if I remember correctly it did NOT update Opera.

I have my home folder on a seperate partition and I’m running Xubuntu 16.04 LTS.

I was surprised to see that a google search of the error message did not turn up any useful results. Any ideas?

How do I deal with Opera showing Facebook images as too small?

I’ve just changed phones, from Lenovo K50 to Xiaomi Redmi 7.

But there’s one problem that I haven’t seen before – images shown are unreadable, simply caused by fact that they’re too small to see anything. I don’t want to change browsers, as Opera allows me to check messages without app.

I’ve tried clearing app data and reinstalling but it gave no result. Any ideas?enter image description here

how to change cache size on opera browser in os x

This was really helpful..Change Google Chrome cache size on OS X for changing cache size in chrome. But i’m trying to convert this command to open opera as larger cache too. I don’t speak.. the language 🙂 but have tried several versions close to the chrome script…with no luck. Can someone point me in the direction to do this w/ opera? tia 🙂 ciara

What internet browsers are able to provide text wrapping (fitting the screen) when zooming (beside Opera)?

I am not sure I am using the proper terms, therefore I will exemplify them with screenshots. Please help me improve my terminology if I am wrong.

(I’m not sure Browser which always allows scale/zoom? is about the same topic, as I don’t grasp the meaning of terms like ” viewport metatag parameters user-scalable” and “meta viewport tag”.)

Taking a Wikipedia page:

enter image description here

Simply zooming it – whether with forced zoom enabled or not – would give this (like in Chrome), where the font size appears larger but the text body is not seen in its entirety, as it doesn’t fit the screen:

while what I would like to see would be this – what I call text fit or text wrap, where the font is enlarged without losing the entirety of the text body, which in this case fits the screen:

I know this is available in Opera. I would like to know what other browsers have this feature.

None of my Web browsers (Chrome, Firefox, Opera) will launch in Win10*WSL*Ubuntu18.04

They all just hang, or barf out some complaints that other Q&As say want nvidia drivers installed, but so doing helps nothing. I think this is because the Win10 / WSL “middleware” is in the way (lspci can’t see any hardware, etc.).

Is there a simple, clean, proven “recipe” for getting X service (VcXsrv) to fully support the graphical applications like web browsers? I currently see a mixed bag, some X apps work and some do not and some utter the usual complaint but “get over it”:

VcXsrv seems kind of “brittle” – when I try to open ‘opera’ and have to ^C to get the command prompt back, X service is then broken until I reboot Win10 – not enough to restart (XLaunch) the VcXsrv or open a new bash terminal. Any ideas about that?

How can Opera browser access my sessions on Google Chrome?

I just installed Opera browser v60 (i.e. Reborn 3) on Windows 10. I noticed that it has automatically (without my consent and permission) taken all my bookmarks in Google Chrome and added to the bookmarks in the Opera browser. In addition, I noticed that somehow it has got access to my open sessions on Google Chrome. By this, I mean that I could for example open some websites using Opera browser without the need to give my username and password since I was logged into them using in Google Chrome browser (e.g. I did not need to login to

This felt creepy and made me think how Opera browser can do this? And in general, should I be worried that this happened and change my usernames and passwords?

At the moment, my idea why this happens is that because both browsers are based on Chromium. But I am not sure if this is the reason.

No sound on Firefox and Opera, but works on Chrome

Ubuntu 18.04.02 Firefox Quantum 65.0.1 Dell inspiron laptop 

There is no sound from Firefox or Opera browsers when playing youtube videos etc. Chrome works fine. Desktop music/video player apps also work without any issues. Neither inbuilt speakers nor headphones work for the problematic browsers.

I’ve gone through the other posts that reported the same problem and tried all the solutions; didn’t solve the issue.

  • Pulse-audio is installed by default. Firefox and Opera show up in the list of applications under sound settings with their respective volume control though.

Sound settings showing browser playback streams

  • Installing ubuntu-restricted-extras didn’t help. I don’t think it’s a codec issue. Playing ogg/flac from wikipedia also makes no sound on firefox.
  • Clearing cache as mentioned in firefox faq didn’t help either.

Redefinindo como uma função opera? C

Olá, estou com uma dúvida em relação a uma linha do código abaixo, vejam:

#include <stdio.h>  typedef float (*TPonteiroFuncao)(float, float); // O QUE ESSA LINHA FAZ?  float soma(float a, float b){     return a+b; }  float produto(float a, float b){     return a*b; }  int main(){     TPonteiroFuncao pfs,pfp;     float r;       pfs = &soma;     pfp = &produto;     r = pfs(12,14);     printf("Resultado: %.2f\n", r);     r = pfp(12,14);     printf("Resultado: %.2f\n", r);      return 0; } 

A linha em questão está redefinindo como as funções criados com o tipo float vão operar? Ou seria apenas a criação de um nome, de modo que toda vez que eu precisar de um ponteiro float basta digitar TPonteiroFuncao?

Qual a necessidade de (float, float); e o que ele faz?
